We describe a link between the ACL2 and HOL mechanical proof assistants that enables the strengths of each system to be deployed smoothly within a single formal development. Severa...

We describe an embedding of the ACL2 logic into higherorder logic. An implementation of this embedding allows ACL2 to be used as an oracle for higher-order logic provers. Categori...

Abstract. Termination poses one of the main challenges for mechanically verifying infinite state systems. In this paper, we develop a powerful and extensible framework based on th...
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...
Gandalf is a first-order resolution theorem-prover, optimized for speed and specializing in manipulations of large clauses. In this paper I describe GANDALF TAC, a HOL tactic that ...
