WebAlonzo Church and J. Barkley Rosser proved in 1936 that lambda calculus has this property; hence the name of the property. (The fact that lambda calculus has this property is also known as the Church–Rosser theorem.) In a rewriting system with the Church–Rosser property the word problem may be reduced to the search for a common … WebHere, we give the theorems for Subject Reduction, Church-Rosser and Strong Normalisation. (For further details and other properties, see [Fen10].) Theorem 5.1 (Subject Reduction for IDRT) If Γ ` M : A and M → N, then Γ ` N : A. Proof. First of all, we have Γ = M : A (by the Soundness Theorem 4.8) and M ⇒ N (since M → N).
