    Comparison of expressive power of some query languages for databases.
    Proceedings of the Steklov Institute of Mathematics, vol.274, Steklov Institute of Mathematics, Moscow , 2011, pages 273288.

    A version of the SQL language and a version of the stratified Datalog are considered, and it is proved that each of these languages can be translated into the other.

    Tributes, Volume 13, Proofs, Categories and Computations, Essays in Honor of Grigori Mints, Soloman Feferman and Wilfried Sieg, editors, College Publications, London , 2010, pages 243 - 250.

    In ``Sverdlovsk notebook" (Sverdlovsk, 1969), I proposed a question: Are any too first-order equivalent finitely generated commutative semigroups isomorphic? In 1970, B.I.Zilber answered the question negatively. A question arises: In what language, any equivalent over the language finitely generated commutative semigroups are isomorphic? In the note, we propose such a language. Moreover, we prove that there is an algorithm which for a given finite set of generators, a given finite set of defining relations of a commutative semigroup for the generators, and a closed formula of the language decides whether the formula holds in the semigroup.

    The collapse result for database query languages.
    Uspehi Matematicheskih Nauk, 61(2): 3 - 66, 2006.

    Russian
    In the survey, we present collapse results in database theory obtained by members of the Tver State University seminar for theoretical foundation of Computer Science. The Isolation and Pseudo-finite Homogeneity properties and universes without independent property are in the focus of our investigations. For these universes, we prove the Baldwin - Benedikt theorem as to reducibility. For reducible theories, we prove the Dudakov's theorem which says that any such theory is bound. For reducible and bound theories, we prove the relative isolation property and the collapse theorem. We note that the notions of reducibility and isolation are equivalent. On the other hand, we present Dudakov's results which show that the effective reducible theories with an effective almost indiscernible sequence have the effective translation of the locally generic extended queries to restricted ones. We also present a Dudakov's example of an expansion of Presburger Arithmetic such that the first-order theory of the expansion is decidable, and the collapse theorem does not hold for the expansion. The example gives a negative answer for known problems.

    Russian
    We propose a problem in PTIME which, we believe, is not in in NLogSpace. If it is the case, it would settle a long staying open problem of Stephen A.Cook posted in 1969.

    as to the collapse theorem. It is investigated so called P-reducible theories. It is proved that, for the P-reducible theories, a version of Pseudo-finite Homogeneity Property holds. So the collapse theorem holds for P-reducible theories.

    Russian
    It is investigated expansions of Presburger's arithmetics by a weakly monotone unary function. For the expansions, it is proposed a sufficient condition for truth of the collapse theorem. The condition holds for the Semenov's functions and for other ones proposed by the author. It is a natural way to organize a quantifier elimination for such an expansion. So, if you can organize a good quantifier elimination for such an expansion, then the collapse theorem holds for the expansion.

    Annals of Pure and Applied Logic, 97(1- 3):85- 125, 1999

    the collapse result theorem was proved for locally generic queries over ordered domains with the Pseudo-finite Homogeneity Property.
    In a very interesting paper of Baldwin and Benedikt the collapse result theorem was proved for locally generic queries over ordered domains without the independence property. It means that over such a domain, order-generic extended queries fail to express more than restricted queries.
    I propose a more general version for the theorem. Actually, for the theories without the independence property, a version of the Pseudo-finite Homogeneity Property holds.

    In Logic, algebra, and computer science. Helena Rasiowa in memoriam, volume 46 of Banach Center Publications, pages 23- 62. Banach Center, Institute of Mathematics, Polish Academy of Sciences, Warszawa, 1999.

    In the relational model of databases a database state is thought of as a finite collection of relations between elements. For many applications it is convenient to pre-fix an infinite domain where the finite relations are going to be defined. Often, we also fix a set of domain functions and/or relations. These functions/relations are infinite by their nature. Some special problems arise if we use such an approach. In the paper we discuss some of the problems.
    We show that there exists a recursive domain with decidable theory in which (1) there is no recursive syntax for finite queries, and in which (2) the state-safety problem is undecidable.
    We provide very general conditions on the FO theory of an ordered domain that ensure collapse of order-generic extended FO queries to pure order queries over this domain: the Pseudo-finite Homogeneity Property and a stronger Isolation Property. We further distinguish one broad class of ordered domains satisfying the Isolation Property, the so-called quasi-o-minimal domains. This class includes all o-minimal domains, but also the ordered group of integer numbers and the ordered semigroup of natural numbers, and some other domains.
    We generalize all the notions to the case of finitely representable database states - as opposed to finite states - and develop a general lifting technique that, essentially, allows us to extend any result of the kind we are interested in, from finite to finitely-representable states. We show, however, that these results cannot be transferred to arbitrary infinite states.
    We prove that safe Datalog-programs do not have any effective syntax.

    If we pre-fix an infinite domain where the elements of the keeping database tables are going to be defined, the problems of finiteness of the answer to a query and of dependence of query language expressibility on the universe signature arise. In the paper we discuss some of the problems.

    Extended order-generic queries.
    Annals of Pure and Applied Logic, 97(1- 3):85- 125, 1999.

    We consider relational databases organized over an ordered domain with some additional relations - a typical example is the ordered domain of rational numbers together with the operation of addition. In the focus of our study are the first-order (FO) queries that are invariant under order-preserving "permutations" - such queries are called order-generic. It has recently been discovered that for some domains order-generic FO queries fail to express more than pure order queries. For example, every order-generic FO query over rational numbers with + can be rewritten without +. For some other domains, however, this is not the case.
    We provide very general conditions on the FO theory of the domain that ensure the collapse of order-generic extended FO queries to pure order queries over this domain: the Pseudo-finite Homogeneity Property and a stronger Isolation Property. We further distinguish one broad class of domains satisfying the Isolation Property, the so-called quasi-o-minimal domains. This class includes all the o-minimal domains, but also the ordered group of integer numbers and the ordered semigroup of natural numbers, and some other domains.
    An important difference of this paper from the recent series of related papers is that we generalize all the notions to the case of finitely representable database states - as opposed to finite states - and develop a general lifting technique that, essentially, allows us to extend any result of the kind we are interested in, from finite to finitely-representable states. We show, however, that these results cannot be transfered to arbitrary infinite states.

    A logic for information systems.
    Studia Logica, 58(1):3- 16, 1997.
    A conception of an information system has been introduced by Pavlak. The study has been continued in works of Pavlak and Orlowska and in works of Vakarelov. They had proposed some basic relations and had constructed a formal system of a modal logic that describes the relations and some of their Boolean combinations. Our work is devoted to a generalization of this approach. A class of relation systems and a complete calculus construction method for these systems are proposed. As a corollary of our main result, our paper contains a solution of a Vakarelov's problem: how to construct a formal system that describes all the Boolean combinations of the basic relations. But having considered an unrestricted in some sense relation set we also present a more formal and general version of this field.

    Safe stratified datalog with integer order does not have syntax.
    ACM Trans. on Database Systems, 23(1):100- 109, 1998.

    Stratified Datalog with integer (gap)-order is considered. A Datalog-program is said to be safe iff its bottom-up processing terminates on all valid inputs. We prove that safe Datalog-programs do not have effective syntax in the sense that there is no recursively enumerable set S of safe Datalog-programs such that every safe Datalog-program is equivalent to a program in S.

    Finite queries do not have effective syntax.
    Information and Computation, 153(1):99- 116, 1999.

    A relational query is called finite, or sometimes safe, iff it yields a finite answer in every database state.
    The set of finite queries of relational calculus is known to be unsolvable. However, in many cases it is possible to impose syntactical restrictions on the class of queries that guarantee finiteness and do not reduce the expressive power of the calculus.
    We show that unfortunately this is not always the case, as we construct a recursive domain with decidable theory where any solvable (or enumerable, for that matter) subclass of queries either contains an infinite query, or misses a finite one.
    Using the same example, we further show undecidability of the problem of state-finiteness, which is, given a query and a database state, to decide upon finiteness of the query in this state.
    This settles two long-standing open problems in the theory of relational databases.

    Flat backtracking prolog for databases: a formal semantics, the computational complexity and the expressibility.
    International Journal of Foundations of Computer Science, 6(1):11- 26, 1995.
    We construct a polynomial-time algorithm for flat PROLOG. Our algorithm gives a new flat PROLOG semantics equivalent to previous one. On the other hand, we show the completeness of flat PROLOG for the polynomial time recognizing. Thus we propose a description of the class PTIME in terms of the computer language PROLOG. We also give a similar descriptions for PSPACE and EXPTIME. For this purpose we consider the extension of flat PROLOG by the mechanism of adding and deleting clauses during the program execution.

    For a dynamic logic L we study dynamic logic Ln for which programs allowed in formulas cannot use more than n variables. We prove that there exists a structure A of a finite signature such that for any natural n, the logic Ln+1 in more expressive over A than Ln.

    A certain canonical form is introduced for formulas of the logic L ∞, w (n), and it is proved that every formula of this logic is equivalent on free algebras to a canonical formula. Do only finitely many programs suffice for expressing all queries expressible in dynamic logic and involving the free algebra under consideration? We answer the question negatively.

    Nondeterminism adds to the expressive power even in presence of quantifiers. This answers Meyer's question. The proof holds in the presence of first-order tests as well as quantifier-free tests.

    Linear logic for nets with bounded resources.

    We introduce a new type of nets with bounded types of distibuted resources (BR-nets). Linear Logic to describe the behaviour of BR-nets is defined. It captures not only consumption of resources but their presence as well. Theorem of soundness and completeness of the proposed axiomatization is proved. The PTIME algorithm for the provability problem is proposed for some particular cases.

    In Selected Papers, 8th EATCS Conference on Computer Science Logic (CSL'94), volume 933 of LNCS, pages 242- 248. Springer-Verlag, 1995.
    By "initial segments of P" we mean classes DTime(nk). The question of whether for any fixed signature the first-order definable predicates in finite models of this signature are all in an initial segment of P is shown to be related to other intriguing open problems in complexity theory and logic, like P=PSpace. The second part of the paper strengthens the result of Ph. Kolaitis of logical definability of unambiguous computations.

    Normalizable linear orders and generic computations in finite models.
    Archive for Mathematical Logic, 38(4):257- 271, 1999.

    We propose an approach that has to do with normalization of a given order (rather than with defining a linear order from scratch). To this end, we show that normalizability of linear order is a strictly weaker condition than definability (say, in the least fixpoint logic), and still allows for extending Immerman-Vardi-style results to generic queries. It seems to be the weakest such condition. We then conjecture that linear order is normalizable in the least fixpoint logic for any finitely axiomatizable class of rigid structures. We also suggest a series of reductions of the conjecture to specialized classes of graphs, which we believe should simplify further work.
