Australasian Computer Science Week 3-7 February 1997, Macquarie University, Sydney, Australia ACSC'97, CATS'97, and ACAC'97 Call for Papers CATS'97 - Computing: The Australasian Theory Symposium 3-4 February 1997 CATS aims at bringing together computing theorists from the Australasian region. Papers are solicited on all aspects of the theory of computer science, including, but not limited to: Category Theory, Complexity, Concurrency, Formal Semantics, Logic, Specification and Verification, and all aspects of the theory of Algorithms (including combinatorial algorithms, distributed algorithms, geometric algorithms, and parallel algorithms). CATS'97 follows on from CATS'94 which was held in Sydney in December 1994, and CATS'96 which was held in Melbourne in February 1996. It is hoped that the meeting will have an `active workshop' atmosphere, with ample time for discussions. Contributions describing work in progress are welcome. Submissions should be sent in Postscript format to cats97@cs.rmit.edu.au by the submission deadline. For final submissions, LaTEX style files and MS Word style sheets will be provided. Authors unable to access or use these style files will be asked to prepare papers of at most ten pages in 10-point, two-column format. Papers will be judged on originality, significance, correctness, and clarity. The contribution of the paper should be clearly explained in both general and technical terms, and authors should make every effort to ensure that the technical content of their papers is understandable by a broad audience. Submission of a paper should be regarded as an undertaking that, should the paper be accepted, at least one of the authors will attend the conference to present the work.
