Nuprl Lemma : interface-at-subtype
∀[Info:Type]. ∀[es:EO+(Info)]. ∀[X:EClass(Top)]. ∀[i:Id]. (E(X@i) ⊆r E(X))
Proof
Definitions occuring in Statement :
es-interface-at: X@i,
es-E-interface: E(X),
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
Id: Id,
subtype_rel: A ⊆r B,
uall: ∀[x:A]. B[x],
top: Top,
universe: Type
