Abstract. Engineering workflow applications are becoming more and more complex, involving numerous interacting business objects within considerable processes. Analysing the interac...
Existing spatial logics for concurrency are intensional, in the sense that they induce an equivalence that coincides with structural congruence. In this work, we study a contextual...
The existence of a final coalgebra is equivalent to the existence of a formal logic with a set (small class) of formulas that has the Hennessy-Milner property of distinguishing co...
In modular approaches to specify concurrent systems a system is built up from components using various operators as e.g. the sequential, the parallel, or the choice (+) operator. U...
