Nuprl Lemma : equal-wf-base-T
∀[T:Type]. ∀[a:Base]. ∀[b:T]. (a = b ∈ T ∈ ℙ)
Proof
Definitions occuring in Statement :
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T,
base: Base,
universe: Type,
equal: s = t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
guard: {T},
implies: P ⇒ Q
