In the ambient logic of classical second order propositional calculus, we solve the specification problem for a family of excluded middle like tautologies. These are shown to be r...
Abstract. The linear lambda calculus is very weak in terms of expressive power: in particular, all functions terminate in linear time. In this paper we consider a simple extension ...
We present a new tableaux calculus deciding the ABox consistency problem for the expressive description logic ALCNHR+ . Prominent language features of ALCNHR+ are number restricti...
Acquiring information about its environment by sensing is a crucial ability of autonomous robots. Based on the established solution to the Frame Problem of the Fluent Calculus, we...
We present a game-theoretic model of the polymorphic -calculus, system F, as a fibred category. Every morphism of the model defines an -expanded, -normal form ^ of system F whose...
