Nuprl Lemma : until-class_local

[Info,B,C:Type]. ∀[X:EClass(B)]. ∀[Y:EClass(C)].  (LocalClass(X)  LocalClass(Y)  LocalClass((X until Y)))


Proof




Definitions occuring in Statement :  until-class: (X until Y) local-class: LocalClass(X) eclass: EClass(A[eo; e]) uall: [x:A]. B[x] implies:  Q universe: Type
Lemmas :  until-class-program_wf local-class_wf eclass_wf es-E_wf event-ordering+_subtype event-ordering+_wf

Latex:
\mforall{}[Info,B,C:Type].  \mforall{}[X:EClass(B)].  \mforall{}[Y:EClass(C)].
    (LocalClass(X)  {}\mRightarrow{}  LocalClass(Y)  {}\mRightarrow{}  LocalClass((X  until  Y)))
