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
