A logic is developed in which function symbols are allowed to represent partial functions. It has the usual rules of logic (in the form of a sequent calculus) except that the subs...
This paper shows a rigorous approach based on algebraic specications and rewriting logic which makes up for the lack of current transformation languages and oers a balanced rigour-...
A text is a word together with an additional linear order on it. We study quantitative models for texts, i.e. text series which assign to texts elements of a semiring. We introduc...
The language of timed µCRL is an extension of an ACP-style process algebra-based language µCRL with time-related features. In this paper we describe this language and its equati...
Logistic systems analysts use a wide array of modeling systems such as algebraic and logic programs. Two simple examples show how they mesh as Constraint Logic programs, emphasizin...
