Nuprl Lemma : simple-comb-1-disjoint-classrel

[Info,T,A,B:Type]. ∀[es:EO+(Info)]. ∀[X:EClass(A)]. ∀[Y:EClass(B)]. ∀[f:A ─→ T].
  (disjoint-classrel(es;A;X;B;Y)  disjoint-classrel(es;T;lifting-1(f)|X|;B;Y))


Proof




Definitions occuring in Statement :  simple-comb-1: F|X| disjoint-classrel: disjoint-classrel(es;A;X;B;Y) eclass: EClass(A[eo; e]) event-ordering+: EO+(Info) uall: [x:A]. B[x] implies:  Q function: x:A ─→ B[x] universe: Type lifting-1: lifting-1(f)
