Nuprl Lemma : hdf-prior_wf
∀[A,B:Type]. ∀[X:hdataflow(A;B)]. ∀[b:bag(B)]. hdf-prior(X;b) ∈ hdataflow(A;B) supposing (↓B) ∧ valueall-type(B)
Proof
Definitions occuring in Statement :
hdf-prior: hdf-prior(X;b),
hdataflow: hdataflow(A;B),
valueall-type: valueall-type(T),
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
squash: ↓T,
and: P ∧ Q,
member: t ∈ T,
universe: Type,
bag: bag(T)
