Approximations of Modal Logic K
Inspired by the recent work on approximating classical logic, we present a procedure that approximates the modal logic K by determining a maximum limit of introspection. This proc...

Labelled Tableaux for Non-normal Modal Logics
In this paper we show how to extend KEM, a tableau-like proof system for normal modal logic, in order to deal with classes of non-normal modal logics, such as monotonic and regular...
