Nuprl Lemma : m-boundary_wf

∀[X,A:Type].  ∀[d:metric(X)]. (m-boundary(X;d;A) ∈ Type) supposing strong-subtype(A;X)


Proof




Definitions occuring in Statement :  m-boundary: m-boundary(X;d;A),  metric: metric(X),  strong-subtype: strong-subtype(A;B),  uimplies: b supposing a,  uall: ∀[x:A]. B[x],  member: t ∈ T,  universe: Type
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  uimplies: b supposing a,  m-boundary: m-boundary(X;d;A),  prop: ℙ

Latex:
\mforall{}[X,A:Type].    \mforall{}[d:metric(X)].  (m-boundary(X;d;A)  \mmember{}  Type)  supposing  strong-subtype(A;X)
