TUTORIALS >> (Tutorial Day: July 28th) << TUTORIALS ! IME-USP, Sao Paulo, Brazil The "5th Workshop on Logic, Language, Information and Computation" (WoLLIC'98), the fifth version of a series of workshops which started in 1994 with the aim of fostering interdisciplinary research in pure and applied logic, will be held in Sao Paulo, Brazil, from July 28th to 31st 1998. Contributions are invited in the form of short papers (6 10pt pages or 1800 words) in all areas related to logic, language, information and computation, including: pure logical systems, proof theory, model theory, algebraic logic, type theory, category theory, constructive mathematics, lambda and combinatorial calculi, program logic and program semantics, logics and models of concurrency, logic and complexity theory, nonclassical logics, nonmonotonic logic, logic and language, discourse representation, logic and artificial intelligence, automated deduction, foundations of logic programming, logic and computation, and logic engineering. The 5th WoLLIC'98 has the scientific sponsorship of the Interest Group in Pure and Applied Logics (IGPL), the European Association for Logic, Language and Information (FoLLI), the Association for Symbolic Logic (ASL), the Sociedade Brasileira de Computacao (SBC), and the Sociedade Brasileira de Logica (SBL). There will be a number of guest speakers, including: Sergei Artemov (Moscow State Univ, Russia) (CONFIRMED), Sam Buss (Univ Calif San Diego, US) (CONFIRMED), Edmund Clarke (Carnegie-Mellon Univ, US) (CONFIRMED), Heinz Dieter Ebbinghaus (Universitaet Freiburg, Germany) (CONFIRMED), Michael Fourman (Edinburgh Univ, UK) (CONFIRMED), Dov Gabbay (Imperial Coll, UK) (*), Hans Kamp (Stuttgart Univ, Germany) (CONFIRMED), Phokion Kolaitis (Univ Calif Santa Cruz, US) (*), Valeria de Paiva (Birmingham Univ, UK) (CONFIRMED), Maarten de Rijke (Amsterdam Univ, The Netherlands) (CONFIRMED), Giovanni Sambin (Padoa Univ, Italy) (CONFIRMED).
