Abstract. This paper presents a formalization of nite and in nite sequences in domain theory carried out in the theorem prover Isabelle. The results are used to model the metatheor...
Given an arbitrary intruder deduction capability, modeled as an inference system S and a protocol, we show how to compute an inference system bS such that the security problem for ...
Parallel and sequential independence are central concepts in the concurrency theory of the double pushout (dpo) approach to graph rewriting. However, so far those same notions were...
Abstract. We present an algorithm for counting the irreducible components of a complex algebraic variety defined by a fixed number of polynomials encoded as straight-line programs ...
Abstract. In many clustering systems (hierarchies, pyramids and more generally weak hierarchies) clusters are generated by two elements only. This paper is devoted to such clusteri...
