Subject: Is cut semantical?
Date: Mon, 25 Aug 1997 11:08:44 -0300 (ADT) [thread overview]
Message-ID: <Pine.OSF.3.90.970825110831.7101G-100000@mailserv.mta.ca> (raw)

From: Vaughan R. Pratt <pratt@cs.stanford.edu>
Cut-free proofs correspond more or less to dinatural transformations,
suitably strengthened to require invariance under logical relations
when necessary. Is there a semantical counterpart in this sense to
proofs with cut? Or is the chaotic nature of cut incompatible with
this sort of syntax-semantics correspondence?
