Nuprl Lemma : eu-Y_wf
∀[e:EuclideanStructure]. (Y ∈ Point)
Proof
Definitions occuring in Statement :
eu-Y: Y,
eu-point: Point,
euclidean-structure: EuclideanStructure,
uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
eu-Y: Y,
spreadn: spread3,
and: P ∧ Q,
prop: ℙ,
all: ∀x:A. B[x],
implies: P ⇒ Q,
so_lambda: λ2x.t[x],
so_apply: x[s]
