Abstract. In this paper we report on our first experiences using the relational analysis provided by the Alloy tool with the theorem prover KIV in the context of specifications of ...
This article presents formalized intuitionistic proofs for the polyhedra genus theorem, the Euler formula and a sufficient condition of planarity. They are based on a hypermap mod...
We prove Kleene theorems for two subclasses of labelled product systems which are inspired from well-studied subclasses of 1bounded Petri nets. For product T-systems we define a c...
