Nuprl Lemma : until-class_wf
∀[Info,A:Type]. ∀[X:EClass(A)]. ∀[Y:EClass(Top)]. ((X until Y) ∈ EClass(A))
Proof
Definitions occuring in Statement :
until-class: (X until Y),
eclass: EClass(A[eo; e]),
uall: ∀[x:A]. B[x],
top: Top,
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
until-class: (X until Y),
eclass: EClass(A[eo; e]),
subtype_rel: A ⊆r B,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2]
Latex:
\mforall{}[Info,A:Type]. \mforall{}[X:EClass(A)]. \mforall{}[Y:EClass(Top)]. ((X until Y) \mmember{} EClass(A))
