This paper gives the first proof that the subtyping relation of a higherorder lambda calculus, Fω ≤, is anti-symmetric, establishing in the process that the subtyping relation...
In this paper we present a formalization of Abadi’s and Cardelli’s theory of objects in the interactive theorem prover Isabelle/HOL. Our motivation is to build a mechanized HOL...
Following earlier work, a modal logic for T-coalgebras is a functor L on a suitable variety. Syntax and proof system of the logic are given by presentations of the functor. This p...
Recent innovations in automatic parallelizing compilers are showing impressive speedups on multicore processors using shared memory with asynchronous channels. We have formulated a...
Abstract. It has often been observed that a point-free style of programvides a more abstract view on programs. We aim to use the gain in abstraction to obtain a denotational semant...
