Towards a Proof Theory of Gödel Modal Logics (1105.1256v2)
Published 6 May 2011 in math.LO and cs.LO
Abstract: Analytic proof calculi are introduced for box and diamond fragments of basic modal fuzzy logics that combine the Kripke semantics of modal logic K with the many-valued semantics of G\"odel logic. The calculi are used to establish completeness and complexity results for these fragments.
