this volume constitutes the proceedings of the 4th international workshop on theorem proving with analytic tableaux and related methods, tableau 95, held at schloß rheinfels, st. goar, germany in may 1995.originally tableau calculi and their relatives were favored primarily as a pedagogical device because of their advantages at the presentation level. the 23 full revised papers in this book bear witness that these methods have now gained fundamental importance in theorem proving, particularly as competitors for resolution methods. the book is organized in sections on extensions, modal logic, intuitionistic logic, the connection method and model elimination, non-clausal proof procedures, linear logic, higher-order logic, and applications
