Kowalski and Sergot's Event Calculus (EC) is a formalism for reasoning about time and change in a logic programming framework. From a description of events which occur in the...
We give a simple intuitionistic completeness proof of Kripke semantics with constant domain for intuitionistic logic with implication and universal quantification. We use a cut-fr...
We consider terms of simply typed lambda calculus in which copy of a subterm may not be inserted to the argument of itself during the reduction. The terms form wide class which inc...
We present a calculus for establishing non-interference of several Java threads running in parallel. The proof system is built atop an implemented sequential Java Dynamic Logic cal...
