Towards a Logical Framework with Intersection and Union Types

Abstract

We present an ongoing implementation of a dependent-type theory (Δ-framework) based on the Edinburgh Logical Framework LF, extended with Proof-functional logical connectives such as intersection, union, and strong (or minimal relevant) implication. Their combination opens up new possibilities of formal reasoning on proof-theoretic semantics. We provide some… (More)
