Abstract. The Spectrum project concentrates on the process of developing well-structured, precise system speci cations. Spectrum is a speci cation language, with a deduction calcul...
In this paper we introduce a logic for parametric polymorphism. Just as LCF is a logic for the simply-typed λ-calculus with recursion and arithmetic, our logic is a logic for Sys...
We prove constructively (in the style of Bishop) that every monotone continuous function with a uniform modulus of increase has a continuous inverse. The proof is formalized, and a...
Abstract. We provide a formal definition of information flows in XML transformations and, more generally, in the presence of type driven computations and describe a sound technique...
Abstract. There is great interest in applying nominal calculi--computational formalisms that include dynamic name generation--to the problems of programming, specifying, and verify...
