Higher order annotated terms for proof search:

Abstract: "A notion of embedding appropriate to higher-order syntax is described. This provides a representation of annotated formulae in terms of the difference between pairs of formulae. We define substitution and unification for such annotated terms. Using this representation of annotated te...

Summary:Abstract: "A notion of embedding appropriate to higher-order syntax is described. This provides a representation of annotated formulae in terms of the difference between pairs of formulae. We define substitution and unification for such annotated terms. Using this representation of annotated terms, the proof search guidance technique of rippling can be extended to higher-order theorems. We illustrate this by several examples based on an implementation of these ideas in [lambda]Prolog."
