In the context of probabilistic verification, we provide a new notion of trace-equivalence divergence between pairs of Labelled Markov processes. This divergence corresponds to the...
The performance of the barrier operation can be crucial for many parallel codes. Especially distributed shared memory systems have to synchronize frequently to ensure the proper o...

The group signature scheme [1], ACJT for short, is popular. In this paper we show that it is not secure. It does not satisfy exculpability. The group manager can sign on behalf of ...
Abstract. We investigate constraint domains in which answers to constraint abduction problems can be represented compactly by a most general answer. We demonstrate several classes ...
Abstract. We propose to use Grothendieck institutions based on 2categorical diagrams as a basis for heterogeneous specification. We prove a number of results about colimits and (so...
