Nuprl Lemma : primed-class_wf
∀[Info,T:Type]. ∀[X:EClass(T)]. (Prior(X) ∈ EClass(T))
Proof
Definitions occuring in Statement :
primed-class: Prior(X),
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,
primed-class: Prior(X),
eclass: EClass(A[eo; e]),
subtype_rel: A ⊆r B,
nat: ℕ,
so_lambda: λ2x.t[x],
prop: ℙ,
and: P ∧ Q,
implies: P ⇒ Q,
so_apply: x[s],
all: ∀x:A. B[x],
or: P ∨ Q,
sq_exists: ∃x:{A| B[x]},
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2]
Latex:
