Nuprl Lemma : es-or-latest_wf
∀[Info,A,B:Type]. ∀[X:EClass(A)]. ∀[Y:EClass(B)]. ((X |- Y) ∈ EClass(one_or_both(A;B)))
Proof
Definitions occuring in Statement :
es-or-latest: (X |- Y),
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 :
one_or_both: one_or_both(A;B),
uall: ∀[x:A]. B[x],
member: t ∈ T,
es-or-latest: (X |- Y),
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(A)]. \mforall{}[Y:EClass(B)]. ((X |\msupminus{} Y) \mmember{} EClass(one\_or\_both(A;B)))
