Nuprl Lemma : es-interface-or-left_wf
∀[Info,A,B:Type]. ∀[X:EClass(one_or_both(A;B))]. (es-interface-or-left(X) ∈ EClass(A))
Proof
Definitions occuring in Statement :
es-interface-or-left: es-interface-or-left(X),
eclass: EClass(A[eo; e]),
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type,
one_or_both: one_or_both(A;B)
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
es-interface-or-left: es-interface-or-left(X),
so_lambda: λ2x y.t[x; y],
subtype_rel: A ⊆r B,
so_apply: x[s1;s2]
Latex:
\mforall{}[Info,A,B:Type]. \mforall{}[X:EClass(one\_or\_both(A;B))]. (es-interface-or-left(X) \mmember{} EClass(A))
