Abstract. We present a proof theoretical method for de-compiling lowlevel code to the typed lambda calculus. We first define a proof system for a low-level code language based on...
This paper analyzes a language for actions and the deontic modalities over actions -- i.e., the modalities permitted, forbidden and obligatory. The work is based on: (1) an action...
Abstract This paper introduces new-HOPLA, a concise but powerful language for higherorder nondeterministic processes with name generation. Its origins as a metalanguage for domain ...
Final coalgebras for a functor serve as semantic domains for state based systems of various types. For example, formal languages, streams, nonwell-founded sets and behaviors of CCS...
Abstract. This paper proposes a tool to support reasoning about (partial) correctness of constraint logic programs. The tool infers a speci cation that approximates the semantics o...
