Automated Reasoning with Analytic Tableaux and Related Methods

This volume contains the research papers presented at the International Con- rence on Automated Reasoning with Analytic Tableaux and Related Methods (TABLEAUX 2002) held on July 30 ¿ August 1, 2002 in Copenhagen, Denmark, in the context of the third Federated Logic Conference (FLoC 2002). This c- ference was the continuation of international meetings on the same topic held in Lautenbach (1992), Marseille (1993), Abingdon (1994), St. Goar (1995), Ter- sini (1996), Pont-`a-Mousson (1997), Oisterwijk (1998), Saratoga Springs (1999), and St Andrews (2000). In 2001 TABLEAUX was part of IJCAR 2001 in - ena. The frame of FLoC 2002 guaranteed once again close contact to the larger Theorem Proving and Logic in Computer Science community. This was in par- cular witnessed by the talk by Matthias Baaz, jointly invited by CADE-18 and TABLEAUX 2002. Tableaux and related methods have been found to be a convenient formalism for automating deduction in various non-standard logics as well as in classical logic. This is nicely illustrated by the wide scope of logics that are covered by the papers collected in this volume: among them are linear logic, temporal - gics, various modal logics, including hybrid logic and multi-modal logics, fuzzy logics like G¿odel- andLuk asiewicz logics, various intermediate logics, quanti?ed boolean logic, and, of course, classical ?rst-order logic in various formats.
