Nuprl Lemma : rel-restriction-implies

∀[T:Type]. ∀[R:T ⟶ T ⟶ ℙ]. ∀[P:T ⟶ ℙ].  R|P => R


Proof




Definitions occuring in Statement :  rel-restriction: R|P,  rel_implies: R1 => R2,  uall: ∀[x:A]. B[x],  prop: ℙ,  function: x:A ⟶ B[x],  universe: Type
Definitions unfolded in proof :  rel-restriction: R|P,  rel_implies: R1 => R2,  infix_ap: x f y,  uall: ∀[x:A]. B[x],  all: ∀x:A. B[x],  implies: P ⇒ Q,  and: P ∧ Q,  member: t ∈ T,  prop: ℙ
