Nuprl Lemma : class-opt_wf
∀[Info,T:Type]. ∀[X:EClass(T)]. ∀[b:Id ⟶ bag(T)]. (X?b ∈ EClass(T))
Proof
Definitions occuring in Statement :
class-opt: X?b,
eclass: EClass(A[eo; e]),
Id: Id,
uall: ∀[x:A]. B[x],
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type,
bag: bag(T)
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
class-opt: X?b,
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:EClass(T)]. \mforall{}[b:Id {}\mrightarrow{} bag(T)]. (X?b \mmember{} EClass(T))
