Nuprl Lemma : valueall-type-has-valueall

∀[T:Type]. ∀[x:T]. has-valueall(x) supposing valueall-type(T)


Proof




Definitions occuring in Statement :  valueall-type: valueall-type(T),  has-valueall: has-valueall(a),  uimplies: b supposing a,  uall: ∀[x:A]. B[x],  universe: Type
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  uimplies: b supposing a,  has-valueall: has-valueall(a),  has-value: (a)↓,  valueall-type: valueall-type(T),  prop: ℙ
