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: supposing a uall: [x:A]. B[x] squash: T and: P ∧ Q member: t ∈ T universe: Type bag: bag(T)

\mforall{}[A,B:Type].  \mforall{}[X:hdataflow(A;B)].  \mforall{}[b:bag(B)].
    hdf-prior(X;b)  \mmember{}  hdataflow(A;B)  supposing  (\mdownarrow{}B)  \mwedge{}  valueall-type(B)
