Title: Beyond “knowing that”: non-standard epistemic logics

Abstract. In this talk I survey our recent line of work on non-standard epistemic logics of “knowing whether”, “knowing what”, and “knowing how”. These modal logics are non-normal yet behave well in the sense that they are usually decidable fragments of first-order or second-order modal logic. In this talk, we will focus on the axiomatizations and expressive power of these logics.
