We define an interpretation of the Isabelle/HOL logic in HOL Light and its metalanguage, OCaml. Some aspects of the Isabelle logic are not representable directly in the HOL Light o...
We developed an importer from both HOL 4 and HOL-light into Isabelle/HOL. The importer works by replaying proofs within Isabelle/HOL that have been recorded in HOL 4 or HOL-light a...
We present a type theory with some proof-irrelevance built into the conversion rule. We argue that this feature is useful when type theory is used as the logical formalism underlyi...
Abstract. Context unification (CU) is the open problem of solving context equations for trees. We distinguish a new decidable variant of CU? well-nested CU ? and present a new unif...
We prove that, if the initial knowledge of the intruder is given by a deterministic bottom-up tree automaton, then the insecurity problem for cryptographic protocols with atomic ke...
