A new coinductive confluence proof for infinitary lambda calculusArticle

Authors: Łukasz Czajka

    We present a new and formal coinductive proof of confluence and normalisation of Böhm reduction in infinitary lambda calculus. The proof is simpler than previous proofs of this result. The technique of the proof is new, i.e., it is not merely a coinductive reformulation of any earlier proofs. We formalised the proof in the Coq proof assistant.
