[T:Type]. ∀[F:(ℕ ⟶ T) ⟶ ℕ].  (strong-continuity2(T;F) ∈ ℙ)


Proof




Definitions occuring in Statement :  strong-continuity2: strong-continuity2(T;F) nat: uall: [x:A]. B[x] prop: member: t ∈ T function: x:A ⟶ B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T strong-continuity2: strong-continuity2(T;F) nat: so_lambda: λ2x.t[x] prop: and: P ∧ Q subtype_rel: A ⊆B so_apply: x[s] uimplies: supposing a le: A ≤ B less_than': less_than'(a;b) false: False not: ¬A implies:  Q all: x:A. B[x] exists: x:A. B[x]
