Logic of proofs LP introduced by S. Artemov in 1995 describes properties of proof predicate “t is a proof of F” in the propositional language extended by atoms of the form [[t...
Abstract. We introduce and study a tactic language, Hitac, for constructing hierarchical proofs, known as hiproofs. The idea of hiproofs is to superimpose a labelled hierarchical n...
We study the behavioural theory of Cardelli and Gordon’s Mobile Ambients. We give an lts based operational semantics, and a labelled bisimulation based equivalence that coincide...
We describe a framework of algebraic structures in the proof assistant Coq. We have developed this framework as part of the FTA project in Nijmegen, in which a constructive proof ...

Abstract. Constraint logic programming combines declarativity and efficiency thanks to constraint solvers implemented for specific domains. Value withdrawal explanations have been ...
