KANELLAKIS AWARD Call for Contributions * The Association for Computing Machinery has instituted a "Kanellakis Award for a theoretical contribution with a significant impact on practice". This award is in memory of Paris C. Kanellakis, who perished in a tragic airplane accident in December 1995. The first Kanellakis Award was given at ACM '97 to Adelman, Diffie, Hellman, Merkle, Rivest, and Shamir for their work on public-key cryptography. * So far, $80,000 have been raised from SIGACT, SIGMOD, the Kannelakis family, and PWS publishing, towards the award endowment. Additional $20,000 are needed to allow the award to be given every year. We should like to provide an opportunity for friends and colleagues of Paris to contribute to the award endowment. We invite pledges to honor Paris and the tradition of scholarly excellence he embodied. Please indicate the amount you wish to pledge by sending email to email@example.com or writing to the following address: ACM Kanellakis Award, c/o Susan Platt, Box 1910, Dept of Computer Science, Providence, RI 02912. ACM will then contact you concerning your (tax deductible) contribution. * Further information.

BOOK ANNOUNCEMENT Bounded Variable Logics and Counting -- A Study in Finite Models Martin Otto Lecture Notes in Logic, vol.9, Springer-Verlag, 1997. ISBN 3-540-62037-0. * This monograph in finite model theory offers a comprehensive treatment of results in the model theory and descriptive complexity theory of infinitary logics with a bounded number of variables and logics with counting constructs. The exposition is largely self-contained, with introductory sections on the relevant logics, model theoretic concepts, and the programme of descriptive complexity. BOOK ANNOUNCEMENT Semantics and Logics of Computation Edited by Andrew M Pitts and P Dybjer Cambridge University Press, January 1997, UKL 35.00 ISBN 0521580579 * The aim of this volume is to present modern developments in semantics and logics of computation in a way that is accessible to graduate students. The book is based on a summer school at the Isaac Newton Institute and consists of a sequence of linked lecture courses. The authors are leaders in their fields and much of material they present was either not previously accessible, or not accessible in such a digestible form. * Contents. S. Abramsky, Semantics of interaction: an introduction to game semantics. T. Coquand, Computational content of classical logic. M. Hofmann, Syntax and semantics of dependent types. M. Hyland, Game semantics. E. Moggi, Metalanguages and applications. A. Pitts, Operationally-based theories of program equivalence. G. Winskel and M. Nielsen, Categories in concurrency. DIMACS WORKSHOP: LOGIC AND ALGORITHMS -- ONE YEAR LATER Rutgers University, July 23-25, 1997 * The 1995-1996 Special Year on Logic and Algorithms (SYLA) was aimed at bridging a dichotomy in computer science between two major branches of research, one in algorithms and complexity, and the other one in models and semantics. SYLA focused on three bridge areas: computer-aided Verification, finite-model Theory, and proof complexity. Computer-Aided Verification studies algorithms and structures for verifying properties of programs. Finite-model theory studies the logical properties of finite structures, and has intimate connections with complexity theory and database theory. Proof complexity studies the length of proofs and the complexity of the inference steps within the proof. SYLA consisted of a 3-week long summer school, 11 workshop, and a federated logic conference. * We are now planning to hold a DIMACS Workshop on "Logic and Algorithms: One Year Later", to take place at Rutgers University, on July 23-25, 1997. The goal of the workshop is to follow up on SYLA. The workshop will cover the three major topics of the Special Year, computer-aided verification, finite-model theory, and proof complexity. We are inviting to the workshop people who participated in the Special Year. We would like them to report on research results that arose during the Special Year or following it. During the Special Year, we conducted many specialized workshops. In this workshop, we are trying to bring the three topics together, in an attempt to provide participants with a broader view of the field. * Organizers: Eric Allender, Robert Kurshan, Moshe Vardi. SUMMER SCHOOL AND WORKSHOP ON NEW PARADIGMS FOR COMPUTATION ON CLASSICAL SPACES Birmingham, 8-10 September 1997 and 11-13 September 1997 * The two events are centered around recent developments in the theory of continuous domains as applied to classical problems in Mathematics and Semantics. These developments are based on ground-breaking work by Abbas Edalat who, using earlier work by Jimmie Lawson, Claire Jones and Gordon Plotkin, showed in the early 90's how a classical (locally compact) space could be embedded as the set of maximal points in a domain. This led to a new theory of integration with applications in the theory of Iterated Function Systems, Neural Networks, Statistical Physics, and Fractal Geometry. More recently, Abbas Edalat and Martin Escardo have made substantial progress on the question of exact real number computation. The Summer School is intended to teach the mathematical background of the theory enabling participants to fully take part in the following Workshop. A small number of grants for the Summer School are available for PhD students. TENTH EUROPEAN SUMMER SCHOOL IN LOGIC, LANGUAGE AND INFORMATION (ESSLLI-98) August 17 - 28, 1998, Saarbruecken, Germany Call for proposals * The ESSLLI-98 Programme Committee invites proposals for introductory and advanced courses, workshops and panels for the 10th annual Summer School on a wide range of topics in the following fields: Logic, Language, Computation, Language and Logic, Logic and Computation, Language and Computation. In addition to courses, workshops and panels, there will be a Student Session. A Call for Papers for the Student Session will be distributed separately. While the Programme Committee welcomes proposals in all of the above areas, for advanced courses, workshops and panel discussions it would especially like to encourage proposals that emphasize cognitive aspects. * Proposal submission. All proposals should be submitted by electronic mail to the program chair, at firstname.lastname@example.org, in plain ASCII text as soon as possible, but no later than June 15, 1997.

The call for papers is now open for the five main conferences of ETAPS'98, with a submission deadline of October 6, 1997. See the ETAPS web page for more details about the scope and submission instructions of each individual conference. MATHFIT SUMMERSCHOOL IN EDINBURGH Games and Computation Laboratory for the Foundations of Computer Science June 23-24, 1997 * The use of games to model various aspects of computation has been notably successful over the past few years. In particular, two areas where there has been rapid progress recently are: game semantics and its applications to programming languages and logic; and the use of games in verifying properties of concurrent processes. Game semantics has been used to give the first syntax-independent constructions of fully abstract models for functional languages such as PCF and FPC, for imperative languages such as Idealized Algol, and for languages with non-local control operators such as call-cc. There are promising applications to object-oriented languages in progress. * Speakers. Samson Abramsky, Martin Hyland, Perdita Stevens, Colin Stirling, Wolfgang Thomas, * Grants. A small number of grants for the Summer School are available for PhD students. * Further information. See the URL above.
