Pitts and Stark have proposed the -calculus as a language for investigating the interaction of unique name generation and higher-order functions. They developed a sound model base...
In this paper I take a dynamic view in the spirit of the update semantics by Veltman (1996) on the first–order model construction procedure presented by Manthey and Bry (1988)....
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 ...
This paper describes the concept of higher order quotients and an implementation in Isabelle. Higher order quotients are a generalization of quotients. They use partial equivalence...
Gregory McColm conjectured that positive elementary inductions are bounded in a class K of nite structures if every (FO + LFP) formula is equivalent to a rst-order formula in K. H...
