As usual, apologies for multiple copies!! SECOND CALL FOR PAPERS LICS'2000 Workshop on Chu Spaces: Theory and Applications Sunday, June 25, 2000, Santa Barbara, California http://www.cs.bham.ac.uk/~vdp/chu.html A Chu space is a related pair of complementary objects. Besides having intrinsic interest in their own right, Chu spaces have found applications to concurrent processes, information flow, linear logic, proof theory, and universal categories. The workshop is concerned with the theory and applications of Chu spaces, as well as related structures such as the Dialectica construction and double glueing. The workshop will bring together computer scientists, mathematicians, logicians, philosophers, and other interested parties to discuss the development of the subject with regard to its foundations, applications, prospects, and directions for future work. Work in the subject is currently fragmented across several areas: category theory, traditional model theory, concurrency, and the semantics of programming languages, and such a workshop can contribute to the coordination and possibly even some unification of these efforts. Suggested topics for presentation and discussion include but are by no means limited to new results about Chu spaces and related structures; their applications to various areas such as concurrency, games, proof theory, etc.; and their implications for foundations and philosophy of computation, mathematics, physics, and other disciplines. The workshop will be held on Sunday, June 25, 2000 at Santa Barbara, California, as an adjunct to the International Conference on Logic in Computer Science (LICS'2000), June 26-29 at the same location as per http://www.cs.bell-labs.com/who/libkin/lics/index.html. Papers within the scope of the workshop are solicited, and may be either work in progress or more mature work. Submission should be in the form of an extended abstract of at most 10 pages, in postscript format, mailed electronically to paiva@parc.xerox.com. Submissions will be evaluated by a committee selected by the organizers, and the full version of accepted papers will be printed in a proceedings available at the start of the workshop. Important dates: Extended abstract: April 25, 2000 Notification of acceptance: May 15, 2000 Proceedings version: June 9, 2000 The workshop will be one full day and is open to all interested researchers.
