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...
Bisimulation quantifiers are a natural extension of modal logics. They preserve the bisimulation invariance of modal logic, while allowing monadic second-order expressivity. Unfort...
Abstract. We present the design of our implemented modal logic programming system MProlog. This system is written in Prolog as a module for Prolog. Codes, libraries, and most featu...
There are two reasons why medieval logic is of interest to modern logician: One is to see how similar it is to modern logic and the other is to see how different it is. We study th...
We introduce our implemented modal logic programming system MProlog. This system is written in Prolog as a module for Prolog. Codes, libraries, and most features of Prolog can be u...
