Proof Normalisation in a Logic Identifying Isomorphic Propositions

pdf-format:


Abstract

We define a fragment of propositional logic where isomorphic propositions, such as A wedge B and B wedge A, or A ==> (B wedge C) and (A ==> B) wedge (A ==> C) are identified. We define System I, a proof language for this logic, and prove its normalisation and consistency.
