A simple modal logic for belief revision

Giacomo Bonanno ()

No 311, Working Papers from University of California, Davis, Department of Economics

Abstract: We propose a modal logic based on three operators, representing intialbeliefs, information and revised beliefs. Three simple axioms are usedto provide a sound and complete axiomatization of the qualitative partof Bayes? rule. Some theorems of this logic are derived concerning theinteraction between current beliefs and future beliefs. Information flowsand iterated revision are also discussed
