Nuprl Lemma : eclass0-bag_wf

[Info,B,C:Type]. ∀[X:EClass(B)]. ∀[f:Id ─→ bag(B) ─→ bag(C)].  (eclass0-bag(f;X) ∈ EClass(C))


Proof




Definitions occuring in Statement :  eclass0-bag: eclass0-bag(f;X) 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)
