Nuprl Lemma : real-has-valueall

∀[x:ℝ]. has-valueall(x)


Proof




Definitions occuring in Statement :  real: ℝ,  has-valueall: has-valueall(a),  uall: ∀[x:A]. B[x]
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  real: ℝ,  so_lambda: λ2x.t[x],  so_apply: x[s],  uimplies: b supposing a,  has-valueall: has-valueall(a),  has-value: (a)↓,  exists: ∃x:A. B[x],  nat_plus: ℕ+,  less_than: a < b,  squash: ↓T,  less_than': less_than'(a;b),  true: True,  and: P ∧ Q,  prop: ℙ
