Paper: Higher-order Unification via Explicit Substitutions (at LICS 1995)

Authors: Gilles Dowek Therese Hardin Claude Kirchner


Higher-order unification is equational unification for beta-eta- conversion. But it is not first-order equational unification, as substitution has to avoid capture. In this paper higher-order unification is reduced to first-order equational unification in a suitable theory: the lambda-sigma-calculus of explicit substitutions.
