Pure and Applied Logic Colloquium Speaker: Christoph Benzmuller On leave from Saarland University Date: Wednesday, November 19, at 4:30 p.m. Place: Baker Hall 237B Title: Automating Access Control Logics and Multimodal Logics in the Automatic Higher-Order Theorem Prover LEO-II Abstract:    LEO-II is a standalone, resolution-based higher-order theorem     prover designed for effective cooperation with specialist     provers for natural fragments of higher-order logic.     At present LEO-II can cooperate with the first-order automated     theorem provers E, SPASS, and Vampire. LEO-II is implemented in    Objective Caml and its problem representation language is the new    TPTP THF language.    We demonstrate that problems in normal multimodal logic and     access control logics can be elegantly encoded simple type theory     and automated in LEO-II.
