Nuprl Lemma : process-subtype

∀[M,E:Type ─→ Type].
  (process(P.M[P];P.E[P]) ⊆r (M[process(P.M[P];P.E[P])]
     ─→ (process(P.M[P];P.E[P]) × E[process(P.M[P];P.E[P])]))) supposing 
     (Continuous+(P.E[P]) and 
     Continuous+(P.M[P]))


Proof




Definitions occuring in Statement :  process: process(P.M[P];P.E[P]),  strong-type-continuous: Continuous+(T.F[T]),  uimplies: b supposing a,  subtype_rel: A ⊆r B,  uall: ∀[x:A]. B[x],  so_apply: x[s],  function: x:A ─→ B[x],  product: x:A × B[x],  universe: Type

\mforall{}[M,E:Type  {}\mrightarrow{}  Type].
    (process(P.M[P];P.E[P])  \msubseteq{}r  (M[process(P.M[P];P.E[P])]
          {}\mrightarrow{}  (process(P.M[P];P.E[P])  \mtimes{}  E[process(P.M[P];P.E[P])])))  supposing 
          (Continuous+(P.E[P])  and 
          Continuous+(P.M[P]))
