Nuprl Lemma : loop-class2_wf

[Info,B:Type]. ∀[X:EClass(B ⟶ B)]. ∀[init:Id ⟶ bag(B)].  (loop-class2(X;init) ∈ EClass(B))


Proof




Definitions occuring in Statement :  loop-class2: loop-class2(X;init) eclass: EClass(A[eo; e]) Id: Id uall: [x:A]. B[x] member: t ∈ T function: x:A ⟶ B[x] universe: Type bag: bag(T)
