A Short Mechanized Proof of the Church-Rosser Theorem by the Z-property for the -calculus in Nominal Isabelle
arXiv:1609.03139
Abstract
We present a short proof of the Church-Rosser property for the lambda-calculus enjoying two distinguishing features: Firstly, it employs the Z-property, resulting in a short and elegant proof; and secondly, it is formalized in the nominal higher-order logic available for the proof assistant Isabelle/HOL.
