In mathematics model theory is the study of (classes of) mathematical structures such as groups fields graphs or even models of set theory using tools from mathematical logic . Model theory has close ties to algebra and universal algebra This article focuses on finitary first order model theory of infinite structures. The model theoretic study of finite structures (for which see finite model theory ) diverges significantly from the study of infinite structures both in terms of the problems studied and the techniques used. Model theory in higher-order logics or infinitary logics is hampered by the fact that completeness does not in general hold for these logics. However, a great deal of study has also been done in such languages. Contents The role of model theory The areas of model theory Universal algebra Finite model theory ...

It may also be described as a study of mathematical structures from the logician's point of view. Model theory at its best is a delightful blend of abstract and concrete reasoning. Among the topics to be treated in this course are Fraisse's characterisation of the notion 'elementary equivalence' (structures A,B are called elementarily equivalent if they satisfy the same first-order-sentences), the compactness theorem and its many consequences, ultraproducts, some non-standard-analysis, Tarski's decision method for the field of real numbers by quantifier elimination and Robinson's notion of model completeness. If time permits, some attention will be given to constructive and recursive model theory.

6th Panhellenic Logic Symposium Volos, Greece, 5-8 July 2007 Programme Thursday 5.7.07 Registration - Opening Constantine Tsinakis (Vanderbilt University): Algebraic Methods in Logic Algebraic logic studies classes of algebras that are related to logical systems, as well as the process by which a class of algebras becomes the algebraic counterpart (semantics)" of a logical system. A field practitioner usually approaches the solution of a problem in logic by first reformulating it in the language of algebra; then by using algebra to solve the reformulated problem; and lastly by expressing the result into the language of logic. A representative association of the preceding kind is the one between the class of Boolean algebras and classical propositional calculus. The focus of this talk is substructural logics and their algebraic counterparts. Substructural logics are non-classical logics that are weaker than classical logic, in the sense that they lack one or more of the structural rules of contraction, weakening and exchange in their Genzen-style axiomatization. (It is, however, convenient to think of the classical logic and intuitionistic logic as substructural logics.) These logics encompass a large number of non-classical logics related to computer science (linear logic), linguistics (Lambek Calculus), philosophy (relevant logics), and multi-valued reasoning. The following are among the objectives of the talk: Propose a uniform framework for the study of the algebraic counter-parts of substructural propositional logics. These algebras, referred to as residuated lattices, have a recently discovered rich structure theory. (Note: The term "residuated lattice" has been used in the literature to refer to algebras that are integral, commutative and bounded. This class and its subclasses are not sufficiently general to provide semantics for all substructural logics.)

Encyclopaedia of Mathematics M Article referred from Article refers to Model theory of valued fields A branch of model theory concerned with the elementary theories of fields with valuations (cf. Elementary theory Field Valuation ). The basic first-order language is that of rings (or fields) together with a unary relation symbol for being an element of the valuation ring, or a binary relation symbol for valuation divisibility (cf. Structure Algebraically closed valued fields. A. Robinson proved that the elementary theory of all algebraically closed valued fields is model complete . It can be deduced from his work that this theory is decidable and admits elimination of quantifiers . If, in addition, the characteristic of the fields and of their residue fields is fixed, then the theory so obtained is complete. The proof uses the fact that all extensions of a valuation of a field to its algebraic closure are conjugate, i.e., the algebraic closures of a valued field are isomorphic as valued fields. Robinson's results have witnessed many applications. The model completeness was applied to valued function fields (cf. Valued function field ).

Additional information Abstract: In the context of rigid analytic spaces over a non-Archimedean valued field, a rigid subanalytic set is a Boolean combination of images of rigid analytic maps. We give an analytic quantifier elimination theorem for (complete) algebraically closed valued fields that is independent of the field; in particular, the analytic quantifier elimination is independent of the valued field's characteristic, residue field and value group, in close analogy to the algebraic case. This provides uniformity results about rigid subanalytic sets. We obtain uniform versions of smooth stratification for subanalytic sets and the ojasiewicz inequalities, as well as a unfiorm description of the closure of a rigid semianalytic set.

Books A Book is a longer document written as a set of notes in the form of a book, and most are intended for publication in some form or other. One of these, Derivation and Computation , has been published already, but I don't have that in electronic form. Some of these books are in good shape, but still need a little polishing. One is little more than a random set of notes. Here is a description of the contents of these documents in approximately in reverse chronological order of writing, that is with the latest at the top and the earliest at the bottom.

Thesis SQEMA an algorithm for computing first-order correspondences in modal logic: an implementation Dimiter Georgiev, Tinko Tinchev and Dimiter Vakarelov Sofia University Here is another interesting example, that is supported in the newer versions of SQEMA, courtesy of Renate Schmidt: p) p)) On the other hand, we are interested in examples of first-order definable modal formulae on which SCAN or DLS succeeds but SQEMA fails. If anyone finds such examples, pease send them to the webmaster . A most important feature of SQEMA is that, as proved in [2] and [3], it only succeeds on canonical (d-persistent) formulae, i.e., whenever successful, it not only computes a local first-order correspondent of the input modal formula, but also proves its canonicity and therefore the canonical completeness of the modal logic axiomatized with that formula. This accoridingly extends to any finite set of modal formulae on which SQEMA suceeds. Thus, SQEMA can also be used as an automated prover of canonical model completeness of modal logics. An implementation in Java of SQEMA was given in [1]. It supports nominals in the input and in the output gives a nominal formula and its translation into a first-order formula. Some simplifications of the first-order formula are also implemented.

He gave a model-theoretic argument, which provides no apparent bounds on the complexity of a decision procedure. We provide a syntactic argument that yields a procedure that is primitive recursive, although not elementary. In particular, we show that it is possible to eliminate a single block of existential quantifiers in time $2^0_O(n)$, where $n$ is the length of the input formula and $2_k^x$ denotes $k$-fold iterated exponentiation.

33. Research Interests All structures described above are model complete; but do they admit Quantifier elimination (say, after adding bounded division) or even a preparation http://www.math.mcmaster.ca/~speisseg/research.html

My research lies in the general areas of model theory and real analytic geometry. (Here is one possible description of how this fits into the general math picture.) The notion of o-minimal expansion of the field of real numbers provides a suitable setting for studying generalizations of the theory of semialgebraic sets, and I try to find new explicit examples of such expansions and study their geometric and model-theoretic properties. Many of these expansions are generated by certain solutions of differential equations, and the hope is to obtain new geometric insights from the o-minimality of these structures. Expanding the real field by large classes of functions As a graduate student at the University of Illinois, I constructed two such examples in joint work with my supervisor Lou van den Dries. Both expand the structure of globally subanalytic sets and define the exponential function. Moreover, one of them (the expansion of the field of reals by certain multisummable series ) also defines the Gamma function on all positive real numbers, while the other (the expansion of the field of reals by all convergent generalized power series ) defines the Riemann zeta function on all real numbers greater than 1. Each of these two examples is generated by the functions, restricted to compact sets, belonging to a certain quasianalytic class satisfying closure properties similar to (but weaker than) the closure properties satisfied by the class of all real analytic functions. Their construction relies on a combination of a form of Weierstrass preparation and blowing-ups due to Jean-Claude Tougeron, used to (locally) resolve the zerosets of functions in the respective class.

Curriculum vitae. A) General data. Born in Bucharest-Romania, 3.03.1940, graduate of the Faculty of Electronics of the Technical University of Bucharest in 1961 and of the Faculty of Mathematics of the University of Bucharest in 1969 with a diplom thesis devoted to the Galois Cohomology, having the late Prof.Ionel Bucur as superviser. In 1977 I defended the PhD thesis with the title "Arithmetic and model theory" at the Faculty of Mathematics of the University of Bucharest under the supervision of Acad. Octav Onicescu, who replaced Prof.Ionel Bucur after his premature death. During the period 1979-1982, with some intrerruptions, I activated as visiting professor at the Institute of Mathematics of the University of Heidelberg thanks to a two years fellowship granted by the Alexander von Humboldt Foundation. As a member of the research group of Algebra and Number Theory, I have been decisively influenced by the personality of my academic mentor Prof. Peter Roquette. In 1983 I obtained a four months fellowship to visit the Universities of Firenze and Camerino-Italy, but unfortunatelly I was prevented from honouring the invitation by the communist Romanian authorities. In 1993 I visited the Universities of Wales-Bangor, Queen Marry-London, and Oxford Mathematical Institute under a three months fellowship granted by the European Communities.

Text Model Theory: An Introduction , by David Marker (Springer GTM). The introduction is available here . More information, including the table of contents, can be found on amazon Recommended reading Some other good introductions to the subject include Model Theory and A Shorter Model Theory , both by Wilfrid Hodges, and A Course in Model Theory by Bruno Poizat. These will be put on reserve in the library. An elegant description of the subject, also by Hodges, can be found here Lecture schedule: (tentative) My aim for the semester is to prove Morley's famous categoricity theorem, which was really the starting point for contemporary model theory. Much of the material covered in chapters 2, 4, and 5 gets used in the proof of this theorem. The ideas, tools, and techniques developed in these chapters are also fundamental to all further developments in the subject. Along the way, we will also examine connections with other areas of mathematics, especially algebra. In particular, chapter 3 contains an extended discussion of the model theory of algebraically closed fields, with glimpses at basic ideas in algebraic geometry.

From one point of view, this is a vibrant area of mathematical research that brings logical methods (in particular the theory of definition) to bear on deep problems of classical mathematics. From another point of view, first-order model theory is the paradigm for the rest of model theory ; it is the area in which many of the broader ideas of model theory were first worked out. 1.

Bounded Model Checking and Induction: From Refutation to Verification In: Proceedings of Computer-Aided Verification, CAV '2003. Authors Abstract We explore the combination of bounded model checking and induction for proving safety properties of infinite-state systems. In particular, we define a general k-induction scheme and prove completeness thereof. A main characteristic of our methodology is that strengthened invariants are generated from failed k-induction proofs. This strengthening step requires quantifier-elimination, and we propose a lazy quantifier-elimination procedure, which delays expensive computations of disjunctive normal forms when possible. The effectiveness of induction based on bounded model checking and invariant strengthening is demonstrated using infinite-state systems ranging from communication protocols to timed automata and (linear) hybrid automata.

Brief introduction to intuitionistic logic is included because the intuitionistic calculus can be obtained from the classical one by only a small modification and in relevant books (Kleene, Takeuti) both calculi are discussed simultaneously. This part of the course hopefully also throws some more light on the concept of soundness and completeness of calculi in general. The philosophical and historical importance of intuitionistic logic is not discussed. Related notions: sequent, antecedent, succedent, Kripke model.

This permits to have a faster proof-search and more readable proofs. But in general case, we loose the cut-elimination property that we had for the sequent calculus, the fact that the cut elimination property holds or not depends on the considered rewrite system. On the other hand, we can express with the help of rewrite rules some powerful theories, such as Higher Order Logic [1] or Peano's arithmetic [2]. The paper [1] introduces a proof search system extending resolution for deduction modulo called Extended Narrowing And Resolution (ENAR). This method is proved complete for rewrite systems for which the cut elimination holds. Conversely, in [4] we have proved that the completness of ENAR implies the cut elimination property for sequent calculus modulo the same rewrite system.

Let A be an L-sentence and let us denote by Gen(A) (generalized spectrum of A) the set of all finite models of A. We say that A represents gen(A). The spectrum S(A) of sentence A is the set of cardinalities of domains of elements of Gen(A) and A is also called a representation of S(A). Let A be some L-sentence and P be a polynomial of degree k of Z[X] asymtotically greater than or equal to identity function on N. We produce a sentence P(A) representing P(S(A)), i.e. S(P(A))=P(S(A)). The algorithm producing P(A) depends only on P and L and effectively one-to-one maps elements of Gen(A) onto elements of Gen(P(A)). This sentence P(A) is formalized in a binary language L* of cardinality 2q+k if k Nadia Creignou, Malika More

Applications of Quantified Constraint Solving over the Reals Bibliography Stefan Ratschan January 2, 2007 Quantified constraints over the reals appear in numerous contexts. Usually existential quantification occurs when some parameter can be chosen by the user of a system, and univeral quantification when the exact value of a parameter is either unknown, or when it occurs in infinitely many, similar versions. The following is a list of application areas and publications that contain applications for solving quantified constraints over the reals.
