Nuprl Lemma : eclass0-single-val

[Info,B,C:Type]. ∀[X:EClass(B)]. ∀[f:Id ─→ B ─→ bag(C)]. ∀[es:EO+(Info)].
  (single-valued-classrel(es;(f X);C)) supposing 
     (single-valued-classrel(es;X;B) and 
     (∀i:Id. ∀b:B.  single-valued-bag(f b;C)))


Proof




Definitions occuring in Statement :  eclass0: (f X) single-valued-classrel: single-valued-classrel(es;X;T) eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) Id: Id uimplies: supposing a uall: [x:A]. B[x] all: x:A. B[x] apply: a function: x:A ─→ B[x] universe: Type single-valued-bag: single-valued-bag(b;T) bag: bag(T)
