Abstract. Both proofs and trust relations play a role in security decisions, in particular in determining whether to execute a piece of code. We have developed a language, called B...
Abstract. This paper studies some relationships between fuzzy relations, fuzzy graphs and fuzzy measure. It is shown that a fundamental theorem of Discrete Convex Analysis is deriv...
We consider an extension of the guarded fragment in which one can guard quantiers using the transitive closure of some binary relations. The obtained logic captures the guarded fr...
A new treatment of data refinement in typed lambda calculus is proposed, phrased in terms of pre-logical relations [HS99] rather than logical relations, and incorporating a constru...
