Usually termination of term rewriting systems TRS's is proved by means of a monotonic well-founded order. If this order is total on ground terms, the TRS is called totally ...
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...
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...
Abstract. Datatype-generic programs are programs that are parameterised by a datatype. Designing datatype-generic programs brings new challenges and new opportunities. We review th...
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...
