Nuprl Lemma : E-prior-class-when
∀[Info:Type]. ∀[es:EO+(Info)]. ∀[X,Y:EClass(Top)]. ∀[d:Top]. (E((X'?d) when Y) = E(Y) ∈ Type)
Proof
Definitions occuring in Statement :
es-prior-class-when: (X'?d) when Y,
es-E-interface: E(X),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
uall: ∀[x:A]. B[x],
top: Top,
universe: Type,
equal: s = t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
es-E-interface: E(X),
subtype_rel: A ⊆r B,
prop: ℙ
Latex:
\mforall{}[Info:Type]. \mforall{}[es:EO+(Info)]. \mforall{}[X,Y:EClass(Top)]. \mforall{}[d:Top]. (E((X'?d) when Y) = E(Y))
