Counterexamples to simulation in non-deterministic call-by-need lambda-calculi with letrec

By Manfred Schmidt-Schauß, Elena Machkasova and David Sabel

Abstract

This note shows that in non-deterministic extended lambda calculi with letrec, the tool of applicative (bi)simulation is in general not usable for contextual equivalence, by giving a counterexample adapted from data flow analysis. It also shown that there is a flaw in a lemma and a theorem concerning finite simulation in a conference paper by the first two authors
