Nuprl Lemma : es-interface-accum_wf

[Info,A,B:Type]. ∀[X:EClass(A)]. ∀[b:B]. ∀[f:B ─→ A ─→ B].  (es-interface-accum(f;b;X) ∈ EClass(B))


Proof




Definitions occuring in Statement :  es-interface-accum: es-interface-accum(f;x;X) eclass: EClass(A[eo; e]) uall: [x:A]. B[x] member: t ∈ T function: x:A ─→ B[x] universe: Type
