Nuprl Lemma : hdf-base-ap-fst

[A,B:Type]. ∀[F:A ─→ bag(B)]. ∀[a:A].  ((fst(hdf-base(m.F[m])(a))) hdf-base(m.F[m]) ∈ hdataflow(A;B))


Proof




Definitions occuring in Statement :  hdf-base: hdf-base(m.F[m]) hdf-ap: X(a) hdataflow: hdataflow(A;B) uall: [x:A]. B[x] so_apply: x[s] pi1: fst(t) function: x:A ─→ B[x] universe: Type equal: t ∈ T bag: bag(T)

\mforall{}[A,B:Type].  \mforall{}[F:A  {}\mrightarrow{}  bag(B)].  \mforall{}[a:A].    ((fst(hdf-base(m.F[m])(a)))  =  hdf-base(m.F[m]))
