Nuprl Lemma : simple-hdf-buffer2_wf

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


Proof




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