We define an “enriched effect calculus” by extending a type theory for computational effects with primitives from linear logic. The new calculus, which generalises intuitionis...
Gentzen’s Hauptsatz – cut elimination theorem – in sequent calculi reveals a fundamental property on logic connectives in various logics such as classical logic and intuition...
A survey is given of results about coherence for categories with finite products and coproducts. For these results, which were published previously by the authors in several places...
Comparative logics were introduced by Casari in the 1980s to treat aspects of comparative reasoning occurring in natural language. In this paper Gentzen systems are defined for the...
Abstract. This paper is concerned about relating formal and computational models of cryptography in case of active adversaries when formal security analysis is done with first ord...
