Call For Papers Fourth International Symposium on Theoretical Aspects of Computer Science (TACS 2001) October 29-31, 2001 Tohoku University, Sendai, Japan http://tacs2001.ito.ecei.tohoku.ac.jp/tacs2001/ The TACS Symposium will focus on the theoretical foundations of programming and their applications. The topics of interest include... Theoretical aspects of the design, semantics, analysis, and implementation of programming languages and systems; logics of programs; calculi and models of concurrency and parallel computation; theories of mobile computation and system security; categories and types in computer science; formalisms, methods, and systems for program specification, verification, synthesis, and optimization; constructive, linear, and modal logics in computer science. The scientific program will consist of invited lectures, contributed talks, and demo sessions. A proceedings containing the full papers of the invited and contributed talks will be published by Springer-Verlag as a volume of Lecture Notes in Computer Science.
