Model-checking problems for PDL (propositional dynamic logic) and its extension PDL (which includes the intersection operator on programs) over various classes of infinite state sy...
Abstract-- The concept of an M-approximative system is introduced. Basic properties of the category of M-approximative systems and in a natural way defined morphisms between them a...
We describe a method for writing assumption/guarantee specifications of concurrent systems. We also provide a proof rule for reasoning about the composition of these systems. Spec...
This paper reports our ongoing research effort to develop a system which translates legal texts into logical forms in which we can check for inconsistency. Our logical formalizati...
This paper presents the Kiel Curry System (KiCS) for the lazy functional logic language Curry. Its main features beyond other Curry implementations are: flexible search control by...
