Nuprl Lemma : simple-hdf-buffer_wf
∀[A,B:Type]. ∀[X:hdataflow(A;B ─→ bag(B))]. ∀[bs:bag(B)].
simple-hdf-buffer(X;bs) ∈ hdataflow(A;B) supposing valueall-type(B)
Proof
Definitions occuring in Statement :
simple-hdf-buffer: simple-hdf-buffer(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)
