Nuprl Lemma : interface-at-val
∀[Info:Type]. ∀[es:EO+(Info)]. ∀[T:Type]. ∀[X:EClass(T)]. ∀[i:Id]. ∀[e:E]. X@i(e) ~ X(e) supposing ↑e ∈b X@i
Proof
Definitions occuring in Statement :
es-interface-at: X@i,
eclass-val: X(e),
in-eclass: e ∈b X,
eclass: EClass(A[eo; e]),
event-ordering+: EO+(Info),
es-E: E,
Id: Id,
assert: ↑b,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
universe: Type,
sqequal: s ~ t
