Point-set embeddings of plane 3-trees
A straight-line drawing of a plane graph G is a planar drawing of G, where each vertex is drawn as a point and each edge is drawn as a straight line segment. Given a set S of n poi...

Dynamical Systems Revisited: Hybrid Systems with Zeno Executions
Results from classical dynamical systems are generalized to hybrid dynamical systems. The concept of limit set is introduced for hybrid systems and is used to prove new results on...

On some Relations between Dynamical Systems and Transition Systems
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...

Resolution of Constraints in Algebras of Rational Trees
Abstract. This work presents a constraint solver for the domain of rational trees. Since the problem is NP-hard the strategy used by the solver is to reduce as much as possible, in...

Detection of dynamic execution errors in IBM system automation's rule-based expert system
We formally verify aspects of the rule-based expert system of IBM's System Automation software for IBM's zSeries mainframes. Starting with a formalization of the expert ...
