We present a system for the formal verication of processors which combines a computer algebra simplication tool with an object-oriented approach. It has been successfully used f...
This article studies preservation of certain algebraic properties of propositional logics when combined by fibring. The logics analyzed here are classified in protoalgebraic, eq...
Process modelling systems are complex and difficult to compare. A key attribute of any process modelling formalism or tool is time which involves how it handles and represents tem...
We show how to compute the planar arrangement induced by segments of arbitrary algebraic curves with the Bentley-Ottmann sweep-line algorithm. The necessary geometric primitives r...
Usually creative telescoping is used to derive recurrences for sums. In this article we show that the non-existence of a creative telescoping solution, and more generally, of a par...
