Bibliography: Set Theory with a Universal Set
Introduction
This is a comprehensive bibliography on axiomatic set theories which have a universal set. (Zermelo-Fraenkel set theory, the most widely studied set theory, does not have a universal set.) This field presently includes three main areas of study: "New Foundations", a set theory devised by W. van Orman Quine , the positive set theory of Helen Skala , and model-based extensions of Zermelo-Fraenkel set theory, initiated by Alonzo Church . Recent papers by Holmes (and the original papers of Andrzej Kisielwicz) on "double extension set theory" are referenced in the main body of the bibliography but not under "recent work"; the jury is still out on this system (two versions of which have been shown to be inconsistent) but if the surviving version is consistent, it must be admitted that it is a set theory with universal set. For those unfamiliar with the field, two places to start are the New Foundations Home Page and Thomas Forster's book Set Theory with a Universal Set . A new option is afforded by the recent appearance of Holmes's elementary text Comments, corrections, and information about new publications should be sent to

03: Mathematical logic and foundations
Introduction
Mathematical Logic is the study of the processes used in mathematical deduction. The subject has origins in philosophy, and indeed it is only by nonmathematical argument that one can show the usual rules for inference and deduction (law of excluded middle; cut rule; etc.) are valid. It is also a legacy from philosophy that we can distinguish semantic reasoning ("what is true?") from syntactic reasoning ("what can be shown?"). The first leads to Model Theory, the second, to Proof Theory. Students encounter elementary (sentential) logic early in their mathematical training. This includes techniques using truth tables, symbolic logic with only "and", "or", and "not" in the language, and various equivalences among methods of proof (e.g. proof by contradiction is a proof of the contrapositive). This material includes somewhat deeper results such as the existence of disjunctive normal forms for statements. Also fairly straightforward is elementary first-order logic, which adds quantifiers ("for all" and "there exists") to the language. The corresponding normal form is prenex normal form. In second-order logic, the quantifiers are allowed to apply to relations and functions to subsets as well as elements of a set. (For example, the well-ordering axiom of the integers is a second-order statement). So how can we characterize the set of theorems for the theory? The theorems are defined in a purely procedural way, yet they should be related to those statements which are (semantically) "true", that is, statements which are valid in every model of those axioms. With a suitable (and reasonably natural) set of rules of inference, the two notions coincide for any theory in first-order logic: the Soundness Theorem assures that what is provable is true, and the Completeness Theorem assures that what is true is provable. It follows that the set of true first-order statements is effectively enumerable, and decidable: one can deduce in a finite number of steps whether or not such a statement follows from the axioms. So, for example, one could make a countable list of all statements which are true for all groups.

    Abstract:
    What's testing? Well, from some point of view, it is a game. Testing tasks can be viewed (and organized!) as games against nature. We introduce and study reachability games. Such games are ubiquitous. A single industrial test suite may involve many instances of a reachability game; hence the importance of optimal or near optimal strategies for reachability games. We find out when exactly optimal strategies exist for a given reachability game, and how to construct them.
    To main page October 27 : Dependence Logic
    Abstract:
    n 1961 Henkin suggested a game theoretic semantics for first order logic and its extension by so called partially ordered quantifiers. It remained an open problem whether this extension and other similar logics could be given a compositional semantics. In 1997 Wilfrid Hodges made a breakthrough in this area by giving a compositional semantics for these logics. In his semantics satisfaction is defined as a relation between formulas and sets of assignments, rather than as a relation between formulas and individual assignments, as is customary in first order logic.
    Based on this idea, we introduce Dependence Logic. This is an extension of first order logic, in which dependence of variables on each other is a basic atomic concept. We give an overview of this logic, its properties, and its applications, from database theory to set theory.

    Historical sketch.
    The idea of constructing a universal language for the whole of mathematics, and of the formalization of proofs on the basis of such a language, was suggested in the 17th century by G. Leibniz . But not until the middle of the 19th century did there appear the first scientific work on the algebraization of Aristotelean logic ( G. Boole , A. de Morgan ). After G. Frege ) and C. Peirce ) put the logic of predicates, variables and quantifiers into the language of algebra, it became possible to apply this language to questions in the foundations of mathematics. On the other hand, the creation of non-Euclidean geometry in the 19th century K. Weierstrass R. Dedekind and G. Cantor , and G. Peano ). In this connection, Peano created a more suitable symbolic representation for the language of logic. Afterwards, this language was perfected in the joint work of B. Russell

    There will be a more serious use of set theory than needed for model to study formal systems of arithmetic, including primitive recursive arithmetic,
    http://logic.cmu.edu/pal-courses-f04.txt
    CARNEGIE MELLON UNIVERSITY PROGRAM IN PURE AND APPLIED LOGIC LOGIC AND LOGIC-RELATED COURSES AND SEMINARS FOR FALL 2004 21-600 Mathematical Logic I Instructor: Peter Andrews MWF 11:30am-12:20pm Baker Hall A53 12 Units Description: The study of formal logical systems which model the reasoning of mathematics, scientific disciplines, and everyday discourse. Propositional calculus and first-order logic. Syntax, axiomatic treatment, derived rules of inference, proof techniques, computer-assisted formal proofs, normal forms, consistency, independence, semantics, soundness, completeness, the Lowenheim-Skolem Theorem, compactness, equality. 21-602 Set theory I INSTRUCTOR: Ernest Schimmerling TuTh 3:00-4:20 pm OSC 201 12 units DESCRIPTION: First semester graduate level set theory. The main topics are ZFC, infinitary combinatorics, relative consistency, constructibility, and descriptive set theory. TEXTBOOK: Kenneth Kunen, "Set Theory : An Introduction to Independence Proofs" COMMENT: Students should have a background in undergraduate level set theory (e.g., 21-229) and logic, which includes a working knowledge of basic ordinal and cardinal arithmetic, G¶del's completeness theorem, and the downward L¶wenheim-Skolem theorem. An understanding of the statement (but not the proof) of G¶del's theorem on consistency proofs will also be assumed. Those without the required background should meet with the instructor as soon as possible to discuss their options, which may include doing some reading over the summer. Set Theory I is a prerequisite for Set Theory II (21-702), which will be taught by Professor Uri Abraham in Spring, 2005. 80-310/610 Logic and Computation Instructor: Jeremy Avigad TuTh 3:00-4:20 pm Hamerschlag Hall B103 12 units Description: Among the most significant developments in logic in the twentieth century is the formal analysis of the notions of provability and semantic consequence. For first-order logic, the two are related by the soundness and completeness theorems: a sentence is provable if and only if it is true in every interpretation. This course begins with a formal description of first-order logic, and proofs of the soundness and completeness theorems. Other topics may include: compactness, the Lowenheim-Skolem theorems, nonstandard models of arithmetic, definability, other logics, and automated deduction. Prerequisites: 80-210, 80-211, or equivalent background in first-order logic. 80-315/615 Modal Logic Instructor: Horacio Arlo-Costa Wed 1:30-3:50 pm Baker Hall 150 9-12 units. Description: An introduction to first-order modal logic. The course considers several modalities aside from the so-called alethic ones (necessity, possibility). Epistemic, temporal or deontic modalities are studied, as well as computationally motivated modals (like "after the computation terminates"). Several conceptual problems in formal ontology that motivated the field are reviewed, as well as more recent applications in computer science and linguistics. Kripke models are used throughout the course, but we also study recent Kripkean-style systematizations of the modals without using possible worlds. Special attention is devoted to Scott-Montague models of the socalled "classical" modalities. Prerequisites: 80-210, or 80-211, or instructor's permission. 1-703 Model theory II INSTRUCTOR: Rami Grossberg MWF 10:30 Baker Hall 231A 12 units DESCRIPTION: This is a second course in model theory. The main topic of discussion will be classification theory for non-elemntary classes. TEXTBOOK: No official text. DETAILS: I will concentrate in what is the deepest part of pure model theory. Namely non-first order theories. In a typical case we will deal with abstract elementary classes. An AEC is essentially a class K of models all of the same similarity type (or a category of sets) which is closed under direct limits and little more. The aim is to have an analysis of such general classes. Most of the material to be discussed appears in (badly written) papers only. I will start with minimal prerequisites, but will progress quickly to some of the research frontieers of the field. I will emphasize aspects of the theory that may eventually converge to a proof cases of Shelah's categoricity conjecture which is the prominent open problem in the field, it is a parallel to Morley's theorem for L ?1,?, most results will be about more general classes. The common to all these classes is that the compactness theorem fails badly. Hopefully some of the techniques will turn to be usefull also in the study of classes of finite models, but we will concentrate at uncountable models. There will be a more serious use of set theory than needed for model theory of first-order logic. PREREQUISITES: About half of a basic graduate course in set theory and parts of an elementary model theory (about 60-70% of 21-603 ) or permission of the instructor. 80-411/711 Proof Theory Instructor: Jeremy Avigad TuTh 10:30-11:50 am Baker Hall 231A 12 units Description: This course is an introduction to Hilbert-style proof theory, where the goal is to represent mathematical arguments using formal deductive systems, and study those systems in syntactic, constructive, computational, or otherwise explicit terms. In the first part of the course, we will study various types of deductive systems (axiomatic systems, natural deduction, and sequent calculi) for classical, intuitionistic, and minimal logic. We will prove Gentzen's cut-elimination theorem, and use it to prove various theorems about first-order logic, including Herbrand's theorem, the interpolation theorem, the conservativity of Skolem axioms, and the existence and disjunction properties for intuitionistic logic. In the second part of the course, we will use these tools to study formal systems of arithmetic, including primitive recursive arithmetic, Peano arithmetic, and subsystems of second-order arithmetic. In particular, we will try to understand how mathematics can be formalized in these theories, and what types of information can be extracted using metamathematical techniques. A solid understanding of the syntax and semantics of first-order logic, as obtained from courses like 80-310/610 or 21-300/600, is required. A course covering issues topics like primitive recursion and coding, like 80-311/611 or 21-700, would be helpful, but is not essential. 15-814 Type Systems for Programming Languages INSTRUCTOR: Robert Harper TuTh 1:30-2:50pm Wean Hall 5409 12 units. DESCRIPTION: This course is an introduction to the theory and practice of type systems for programming languages. Topics include typed lambda calculus, subtyping, polymorphism, data abstraction, recursive types, and objects. PREREQUISITE: Background equivalent to programming skills and programming language exposure afforded by a typical undergraduate Computer Science degree. TEXTBOOK: Benjamin Pierce "Types and Programming Languages" MIT Press 2002. COMMENT: This course satisfies the CS distribution requirement in programming languages.

    Peano axioms
    From Wikipedia, the free encyclopedia
    (Redirected from Peano arithmetic Jump to: navigation search In mathematical logic , the Peano axioms , also known as the Dedekind-Peano axioms or the Peano postulates , are a set of axioms for the natural numbers presented by the 19th century Italian mathematician Giuseppe Peano . These axioms have been used nearly unchanged in a number of metamathematical investigations, including research into fundamental questions of consistency and completeness of number theory The need for formalism in arithmetic was not well appreciated until the work of Hermann Grassmann , who showed in the 1860s that many facts in arithmetic could be derived from more basic facts about the successor operation and induction In 1888, Richard Dedekind proposed a collection of axioms about the numbers, and in 1889 Peano published a more precisely formulated version of them as a collection of axioms in his book, The principles of arithmetic presented by a new method Latin rithmetices principa, nova methodo exposita

    On an arithmetic in a set theory within ukasiewicz logic
    Shunsuke Yatabe
    A significance of the set theory with the comprehension principle is to allow a general form of the recursive definition []: For any formula j j (x, ..., z)] within CFLew , i.e. we can define a set z by using a parameter z itself. This allows us to represent any partial recursive function on w Let H is a set theory with the comprehension principle within ukasiewicz infinite-valued predicate logic with its standard semantics. It has been conjectured that H is enough strong to develop an arithmetic because the recursive definition on w can be used in place of mathematical induction: We review about this. The arithmetic in H is somehow similar to one in "non-standard models" of PA . For example, we can prove an

      Abstract
      In this paper, we consider certain cardinals in ZF #set theory without AC, the Axiom of Choice#. In ZFC #set theory with AC#, given any cardinals C and D; either C # D or D # C: However, in ZF this is no longer so. For a given in#nite set A consider seq 1 1 #A#, the set of all sequences of A without repetition. We compare seq 1 1 #A# , the cardinality of this set, to P#A# , the cardinality of the power set of A. What is provable about these two cardinals in ZF? The main result of this...

    Special Issue on the Linkages Between Interval Mathematics and Fuzzy Set Theory
    Guest editor: Weldon A. Lodwick Reliable Computing will devote a special issue to papers that address the interrelationship between interval mathematics and fuzzy set theory. The connection between interval mathematics and fuzzy set theory is evident in the extension principle, arithmetic, logic, and in the mathematics of uncertainty. Much of the research to date has been in the use of interval mathematics in fuzzy set theory, in particular fuzzy arithmetic and fuzzy interval analysis. This may be because intervals can be considered as a particular type of fuzzy set. The impact of fuzzy set theory on interval mathematics is not quite as evident. For example, it is clear that fuzzy logic, fuzzy control, fuzzy neural networks, and fuzzy cluster analysis, are four important areas of fuzzy set theory. The impact of interval analysis on these four areas is not as apparent. Can the development in these areas of fuzzy set theory inform research in interval mathematics?

    • Inner Models and Fine Structure Infinite Combinatorics Equiconsistency Results Large Cardinals
    Set Theory was invented by Georg Cantor (1845 - 1918), and revolutionized mathematics. It's main theme is infinity. The research areas of modern set theory are:
  • The theory of ZFC Large Cardinals Inner Models and Fine Structure Descriptive Set Theory Forcing Infinite Combinatorics
    • Set Theory provides an universal framework in which all of mathematics can be interpreted. There is no competing theory in that respect. A well-known formulation of the basic set theoretic principles is given by the axiomatic system ZFC of Ernst Zermelo and Abraham Fraenkel, formalized in first order logic (the C denotes the axiom of choice).
    ZFC, however, does not decide the size of the reals: Cantor's Continuum Hypothesis (CH) is independent of ZFC (Goedel 1938, Cohen 1963). This result marks the beginning of modern Set Theory.
    Not only (CH) but many other propositions were shown to be independent. The methods used to prove independence are inner models - natural realizations of the axioms, the most prominent being Goedel's constructible universe L - and forcing - Cohen's method to enlarge given models of set theory keeping control of the new sets.

    Abstract:     [Plain Text Version] We present a polynomial time algorithm for learning a large class of algebraic models of computation. We show that any arithmetic circuit whose partial derivatives induce a low-dimensional vector space is exactly learnable from membership and equivalence queries. As a consequence, we obtain polynomial-time algorithms for learning restricted algebraic branching programs as well as noncommutative set-multilinear arithmetic formulae. In addition, we observe that the algorithms of Bergadano et al. (1996) and Beimel et al. (2000) can be used to learn depth-3 set-multilinear arithmetic circuits. Previously only versions of depth-2 arithmetic circuits were known to be learnable in polynomial time. Our learning algorithms can be viewed as solving a generalization of the well known polynomial interpolation problem where the unknown polynomial has a succinct representation. We can learn representations of polynomials encoding

A considerable advance in nineteenth-century mathematics was the introduction of rigour to suspect areas of analysis. The notion of `real number,' for example, can now be defined in terms of Cauchy sequence or Dedekind cut. Both of these are generally acceptable reductions of the intuitive continuum of real numbers to sets of sets or sequences of rational numbers.

    Appendix 1. About Model Theory
    Some widespread Platonist superstitions were derived from other important results of mathematical logic (omitted in the main text of this book): Goedel's completeness theorem for predicate calculus, Loewenheim-Skolem theorem, the categoricity theorem of second order Peano axioms. In this short Appendix I will discuss these results and their methodological consequences (or lack of them). All these results have been obtained by means of the so-called model theory . This is a very specific approach to investigation of formal theories as mathematical objects. Model theory is using the full power of set theory. Its results and proofs can be formalized in the set theory ZFC Model theory is investigation of formal theories in the metatheory ZFC. The main structures of model theory are interpretations . Let L be the language of some (first order) formal theory containing constant letters c , ..., c

    Thoralf Albert Skolem
    Born: 23 May 1887 in Sandsvaer, Buskerud, Norway
    Died: 23 March 1963 in Oslo, Norway
    Thoralf Skolem 's parents were Helene Olette Vaal and Even Skolem, who was primary school teacher. Although his father was a teacher, Thoralf came from a farming family with most of his relations being farmers. He attended secondary school taking the final examination, the Examen artium, in Kristiania (later renamed Oslo) in 1905. He then entered Kristiania University to study mathematics, but he also took courses on physics, chemistry, zoology and botany. In 1909 Skolem took a job as assistant to the physicist Kristian Birkeland, who was famed for his experiments with the aurora-like effect obtained by bombarding a magnetized sphere with electrons, and Skolem's first publications were physics papers written jointly with Birkeland. Skolem took his state examination in 1913, passing with distinction. His dissertation Undersokelser innenfor logikkens algebra ... Viggo Brun and Skolem agreed that neither of them would bother to obtain the degree of Doctor, probably feeling that, in Norway, it served no useful function in the education of a young scientist. Skolem became a Docent in Mathematics in Kristiania in 1918, and in the same year he was elected to the Norwegian Academy of Science and Letters. Despite his earlier agreement with Viggo Brun, he decided to submit a thesis for a doctorate in 1926 [5]:-

    Logic: Research
    Some Specific Projects Research Support, Collaborations and Exchange Programs Research done by members of our group tends to be centered in model theory and its applications and in descriptive set theory. There are also research projects involving other members of the Mathematics Department, especially in nonstandard analysis and in aspects of group theory that have significant connections to logic. Much of this work emphasizes the interactions between logic and other parts of mathematics. Recent successes based on these connections demonstrate that mathematical logic can provide powerful new methods for many areas of mathematics and can be the basis for breakthroughs on critical problems. Logic typically comes into the picture in two ways: (a) it provides a new set of tools; (b) it provides a new language within which to formulate results and problems. Some Specific Projects These brief descriptions give representative examples of the research projects that members of our group are involved in. Van den Dries has in recent years pursued research on three fronts:

    Set theory and its neighbours , nineth meeting:
    The nineth one-day conference in the in the series Set theory and its neighbours , took place on Wednesday, 25th April 2001 at the London Mathematical Society building, De Morgan House, 57-58 Russell Square, London WC1. The speakers at the meeting were:
    • Russell Barker (Oxford), Robinson-type relations and the relationship between the k-size and cardinality of finite structures
        In this talk I will introduce the notions of L^k, the restriction of first order logic to k-variables, the k-size of a model and, two conjectures proposed by Anuj Dawar. Then I shall define define a special kind of relation which I shall call a Robinson-type relation and prove some results about these relations. I shall go on to give a translation between these relations and the set of L^3 theories and then use the earlier results to disprove Dawar's second conjecture.
    • (UEA), Combinatorial principles that follow from GCH-like cardinal arithmetic assumptions
        Abstract: We discuss various results showing that at certain cardinals diamond-like principles follow just from local GCH-like assumptions on cardinal arithmetic.

    Shimura Curves
      Notes from my 2005 ISM course:
      These are all the notes I typed up for my 2005 ISM course on Shimura varieties. In the lectures, I presented more material on Hilbert and Siegel modular varieties, adelic double coset constructions, and strong approximation than has survived in the lecture notes. Most of the omitted material is of a rather standard sort it appears in many places which is not to say that it shouldn't appear here as well. The reader will notice that the notes are significantly more polished at the beginning and the end than in the middle. I am quite pleased with the very last lecture, which seems to put some of the pieces of the theory together in a new way. I would like to see more detail on arithmetic groups and lots more detail on quaternion orders and trace formulas. Inevitably for notes of this length, the most important results like the existence of rational and integral canonical models get stated and kicked around a bit but not proved. To remedy this will require significantly more work.

These results are discussed in detail below. THE COMPLETENESS THEOREM (1929) In 1928, David Hilbert and Wilhelm Ackermann published , a slender but potent text on the foundations of logic. In this text they posed the question of whether a certain system of axioms for the first-order predicate calculus is complete, i.e., whether every logically valid sentence in first-order logic can be derived from the

    2.3 Approaches for Representation of Uncertainty
    Various approaches for representing uncertainty in the context of different domains of applicability are presented by Klir [ ], and are briefly summarized in the following:
    • Classical set theory: Uncertainty is expressed by sets of mutually exclusive alternatives in situations where one alternative is desired. This includes diagnostic, predictive and retrodictive uncertainties. Here, the uncertainty arises from the nonspecificity inherent in each set. Large sets result in less specific predictions, retrodictions, etc., than smaller sets. Full specificity is obtained only when one alternative is possible.
    • Probability theory: Uncertainty is expressed in terms of a measure on subsets of a universal set of alternatives (events). The uncertainty measure is a function that, according to the situation, assigns a number between and 1 to each subset of the universal set. This number, called probability of the subset, expresses the

    Model Theory: an Introduction

    Springer Graduate Texts in Mathematics 217
    Introduction
    Model theory is a branch of mathematical logic where we study mathematical structures by considering the first-order sentences true in those structures and the sets definable by first-order formulas. Traditionally there have been two principal themes in the subject:
    • starting with a concrete mathematical structure, such as the field of real numbers, and using model-theoretic techniques to obtain new information about the structure and the sets definable in the structure;
    • looking at theories that have some interesting property and proving general structure theorems about their models.
    A good example of the first theme is Tarski's work on the field of real numbers. Tarski showed that the theory of the real field is decidable. This is a sharp contrast to Godel's Incompleteness Theorem, which showed that the theory of the seemingly simpler ring of integers is undecidable. For his proof, Tarski developed the method of quantifier elimination which can be used to show that all subsets of R^n definable in the real field are geometrically well-behaved. More recently, Wilkie extended these ideas to prove that sets definable in the real exponential field are also well-behaved.
    For some time, these two themes seemed like opposing directions in the subject, but over the last decade or so we have come to realize that there are fascinating connections between these two lines. Classical mathematical structures, such as groups and fields, arise in surprising ways when we study general classification problems, and ideas developed in abstract settings have surprising applications to concrete mathematical structures. The most striking example of this synthesis is Hrushovski's application of very general model-theoretic methods to prove the MordellLang Conjecture for function fields.
