Abstract. Well-known hierarchies discriminate between the computational power of discrete time and space dynamical systems. A contrario the situation is more confused for dynamical...
Abstract. The Abstract State Machines (ASM) methodology is a methodology for formally specifying computing systems. We use the ASM methodology to give the dynamic semantics of the ...
Abstract. In this paper we de ne a precise notion of abstraction relation between continuous dynamical systems and discrete state-transition systems. Our main result states that ev...
This tutorial paper discusses a particular style of operational semantics that enables one to give a ‘syntax-directed’ inductive definition of termination which is very useful...
Abstract. Given a nite state machine denoting the specication of a system, nding some short interaction sequences capable to reach some/all states or transitions of this machine...
