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