Nuprl Lemma : hdf-compose0_wf
∀[A,B,C:Type]. ∀[f:B ─→ bag(C)]. ∀[X:hdataflow(A;B)]. hdf-compose0(f;X) ∈ hdataflow(A;C) supposing valueall-type(C)
Proof
Definitions occuring in Statement :
hdf-compose0: hdf-compose0(f;X),
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)
