Nuprl Lemma : hdf-sequence_wf

[A,B,C:Type]. ∀[X:hdataflow(A;B)]. ∀[Y:hdataflow(A;C)]. ∀[Z:hdataflow(A;B)].
  hdf-sequence(X;Y;Z) ∈ hdataflow(A;B) supposing valueall-type(B)


Proof




Definitions occuring in Statement :  hdf-sequence: hdf-sequence(X;Y;Z) hdataflow: hdataflow(A;B) valueall-type: valueall-type(T) uimplies: supposing a uall: [x:A]. B[x] member: t ∈ T universe: Type
Definitions unfolded in proof :  hdf-sequence: hdf-sequence(X;Y;Z) member: t ∈ T uall: [x:A]. B[x] all: x:A. B[x] implies:  Q uimplies: supposing a so_lambda: λ2x.t[x] so_apply: x[s] so_lambda: λ2y.t[x; y] so_apply: x[s1;s2]

Latex:
\mforall{}[A,B,C:Type].  \mforall{}[X:hdataflow(A;B)].  \mforall{}[Y:hdataflow(A;C)].  \mforall{}[Z:hdataflow(A;B)].
    hdf-sequence(X;Y;Z)  \mmember{}  hdataflow(A;B)  supposing  valueall-type(B)
