University of Pennsylvania Department of Computer and Information Science Technical Report No. MS-CIS-91-97. ABSTRACT: The extensions of first-order logic with a least fixed point operators (FO + LFP) and with a partial fixed point operator (FO + PFP) are known to capture the complexity classes P and PSPACE respectively in the presence of an ordering relation over finite structures. Recently, Abiteboul and Vianu [AV91b] investigated the relation of these two logics in the absence of an ordering, using a mchine model of generic computation. In particular, they showed that the two languages have equivalent expressive power if and only if P = PSPACE. These languages can also be seen as fragments of an infinitary logic where each formula has a bounded number of variables, L (see, for instance, [KV90]). We present a treatment of the results in [AV91b] from this point of view. In particular, we show that we can write a formula of FO + LFP and P from ordered structures to classes of structures where every element is definable. We also settle a conjecture mentioned in [AV91b] by showing that FO + LFP in properly contained in the polynomial time computable fragment of

Querying Spatial Databases via Topological Invariants. Luc Segoufin Victor Vianu : Querying Spatial Databases via Topological Invariants. PODS 1998 DBLP BibTeX Abstract The paper investigates the use of topological annotations (called topological invariants) to answer topological queries in spatial databases. The focus is on the translation of topological queries against the spatial database into queries against the topological invariant. The languages considered are first-order on the spatial database side, and fixpoint and first-order on the topological invariant side. In particular, it is shown that fixpoint expresses precisely the ptime queries on topological invariants. Load The ACM SIGMOD Anthology, CDROM Edition, Volume 1-3, PODS '82-'98. and ...

Abstract The Boundedness Problem for Monadic Universal First-Order Logic Proceedings of 21th IEEE Symposium on Logic in Computer Science LICS 2006, pp 37-46. Abstract Consider the monadic boundedness problem for least fixed points over FO formulae as a decision problem: Given a formula that is positive in $X$, decide whether there is a uniform finite bound on the least fixed point recursion based on this formula. Few fragments of FO are known to have a decidable boundedness problem; boundedness is known to be undecidable for many fragments. We here show that monadic boundedness is decidable for purely universal FO formulae without equality in which each non-recursive predicate occurs in just one polarity (e.g., only negatively). The restrictions are shown to be essential: waving either the polarity constraint or allowing positive occurrences of equality, the monadic boundedness problem for universal formulae becomes undecidable. The main result is based on a model theoretic analysis involving ideas from modal and guarded logics and a reduction to the monadic second-order theory of trees.

Infinitary Logic and Inductive Definability over Finite Structures A. Dawar S. Lindell and S. Weinstein Information and Computation 119 (1995), pp 160-175. The extensions of first-order logic with a least fixed point operator (FO + LFP) and with a partial fixed point operator (FO + PFP) are known to capture the complexity classes P and PSPACE respectively in the presence of an ordering relation over finite structures. Recently, Abiteboul and Vianu investigated the relationship of these two logics in the absence of an ordering, using a machine model of generic computation. In particular, they showed that the two languages have equivalent expressive power if and only if P = PSPACE. These languages can also be seen as fragments of an infinitary logic where each formula has a bounded number of variables. We investigate this logic of finite structures and provide a normal form for it. We also present a treatment of the results of Abiteboul and Vianu from this point of view. In particular, we show that we can write a formula of FO + LFP that defines an ordering of the L k types uniformly over all finite structures. One consequence of this is a generalization of the equivalence of FO + LFP and P from ordered structures to classes of structures where every element is definable. We also show that FO + LFP is properly contained in the polynomial time computable fragment of L

Title of proposed conference: Computability Theory and Applications 3. Organizing committee: Peter Cholak, University of Notre Dame Steffen Lempp (co-chair), University of Wisconsin Manuel Lerman (co-chair), University of Connecticut Richard Shore (co-chair), Cornell University 4. Program information: 4.1. Program summary: Pure computability theory On the other hand, Cooper has recently claimed that there is a nontrivial automorphism of the Turing degrees and indeed of the computably enumerable degrees that shows that these definability results are, in a certain way, the best possible. If Cooper's construction can be understood and applied elsewhere it will provide an entry into a whole new realm of nondefinability results. Computable mathematics Another version of many of these questions is investigated in reverse mathematics as developed by H. Friedman and Simpson. This approach is, on its face, a proof-theoretic and foundational investigation into the axiomatic systems needed to prove standard theorems of classical mathematics. On closer scrutiny, one sees that many of the arguments and results in this area can also be viewed as ones in computable mathematics. There is an almost perfect translation between the proof-theoretic systems used and the established levels of complexity in computability. Each approach, however, contributes its own techniques and often produces results with overlapping but supplementary content.

As a case study, one can consider the notion of innocent strategy which is the basis for a game semantical interpretation of proofs and programmes. Some combinatorial content of this notion is sketched in the joint LICS paper accompanying this talk, whose abstract reads as follows.

Newsletter 33 April 9, 1996 FLOC TRAVEL BULLETIN * Olympics! The 1996 Olympic Games take place from July 19 to Aug 3rd in Atlanta. This period is also peak tourist season. We have some anecdotal evidence that it is difficult already to get flights to New York and other places for specific days during that time. * Further Information. For the most up-to-date information on FLoC, see the web page. Full travel information will soon be available, but for now the web page has a link to information on travelling to DIMACS. DIMACS is on the Busch campus of Rutgers. FLoC will be held on the College Avenue campus of Rutgers which is just a few miles away. WORKSHOP ON RELEVANCE IN KNOWLEDGE REPRESENTATION AND REASONING 1ST INT'L WORKSHOP ON REWRITING LOGIC AND ITS APPLICATIONS September 3-6, 1996, Asilomar, Pacific Grove, California * Topics. Foundations, models, and extensions of rewriting logic (RWL); uses of rewriting logic as a logical framework; applications of RWL to the specification of languages and systems; applications of RWL to object-oriented specification and programming; applications of RWL to concurrency and parallel programming; programming languages based on rewriting logic. * Submissions. 2,000 word abstract submitted electronically (in postcript format) to the program chair (meseguer@csl.sri.com). Submission of abstracts due to program chair May 1, 1996. * Program Committee. Fiorella De Cindio, Kokichi Futatsugi, Claude Kirchner, Christian Lengauer, Narciso Marti-Oliet, Jose Meseguer, Ugo Montanari, Carolyn Talcott. * Invited Speakers. Narciso Marti-Oliet, Ugo Montanari, Martin Wirsing.
