Nuprl Lemma : m-open-cover_wf

[X:Type]. ∀[d:metric(X)]. ∀[I:Type]. ∀[A:I ⟶ X ⟶ ℙ].  (m-open-cover(X;d;I;i,x.A[i;x]) ∈ ℙ)


Proof




Definitions occuring in Statement :  m-open-cover: m-open-cover(X;d;I;i,x.A[i; x]) metric: metric(X) uall: [x:A]. B[x] prop: so_apply: x[s1;s2] member: t ∈ T function: x:A ⟶ B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T m-open-cover: m-open-cover(X;d;I;i,x.A[i; x]) prop: and: P ∧ Q all: x:A. B[x] so_lambda: λ2x.t[x] so_apply: x[s1;s2] so_apply: x[s] exists: x:A. B[x] subtype_rel: A ⊆B
