Nuprl Lemma : eclass2-program-wf-hdf

[Info,B,C:Type].
  ∀[Xpr:Id ─→ hdataflow(Info;B ─→ bag(C))]. ∀[Ypr:Id ─→ hdataflow(Info;B)].  (Xpr Ypr ∈ Id ─→ hdataflow(Info;C)) 
  supposing valueall-type(C)


Proof




Definitions occuring in Statement :  eclass2-program: Xpr Ypr Id: Id valueall-type: valueall-type(T) uimplies: supposing a uall: [x:A]. B[x] member: t ∈ T function: x:A ─→ B[x] universe: Type bag: bag(T) hdataflow: hdataflow(A;B)
Lemmas :  hdf-compose2_wf Id_wf hdataflow_wf bag_wf valueall-type_wf

Latex:
\mforall{}[Info,B,C:Type].
    \mforall{}[Xpr:Id  {}\mrightarrow{}  hdataflow(Info;B  {}\mrightarrow{}  bag(C))].  \mforall{}[Ypr:Id  {}\mrightarrow{}  hdataflow(Info;B)].
        (Xpr  o  Ypr  \mmember{}  Id  {}\mrightarrow{}  hdataflow(Info;C)) 
    supposing  valueall-type(C)
