Nuprl Lemma : es-E-interface-conditional-subtype2

∀[Info:Type]. ∀[es:EO+(Info)]. ∀[X,Y:EClass(Top)].  (E(Y) ⊆r E([X?Y]))


Proof




Definitions occuring in Statement :  es-E-interface: E(X),  cond-class: [X?Y],  eclass: EClass(A[eo; e]),  event-ordering+: EO+(Info),  subtype_rel: A ⊆r B,  uall: ∀[x:A]. B[x],  top: Top,  universe: Type
Lemmas :  cond-class-subtype2,  top_wf,  eclass_wf,  es-E_wf,  event-ordering+_subtype,  event-ordering+_wf
\mforall{}[Info:Type].  \mforall{}[es:EO+(Info)].  \mforall{}[X,Y:EClass(Top)].    (E(Y)  \msubseteq{}r  E([X?Y]))
