Nuprl Lemma : hdf-buffer2_wf

∀[A,B:Type]. ∀[X:hdataflow(A;B ─→ B)]. ∀[bs:bag(B)].  hdf-buffer2(X;bs) ∈ hdataflow(A;B) supposing valueall-type(B)


Proof




Definitions occuring in Statement :  hdf-buffer2: hdf-buffer2(X;bs),  hdataflow: hdataflow(A;B),  valueall-type: valueall-type(T),  uimplies: b supposing a,  uall: ∀[x:A]. B[x],  member: t ∈ T,  function: x:A ─→ B[x],  universe: Type,  bag: bag(T)
