Nuprl Lemma : rel_plus_transitivity

∀[T:Type]. ∀[R:T ⟶ T ⟶ ℙ]. ∀[x,y,z:T].  ((R+ x y) ⇒ (R+ y z) ⇒ (R+ x z))


Proof




Definitions occuring in Statement :  rel_plus: R+,  uall: ∀[x:A]. B[x],  prop: ℙ,  implies: P ⇒ Q,  apply: f a,  function: x:A ⟶ B[x],  universe: Type
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  implies: P ⇒ Q,  rel_plus: R+,  exists: ∃x:A. B[x],  member: t ∈ T,  nat_plus: ℕ+,  all: ∀x:A. B[x],  decidable: Dec(P),  or: P ∨ Q,  uimplies: b supposing a,  not: ¬A,  satisfiable_int_formula: satisfiable_int_formula(fmla),  false: False,  top: Top,  and: P ∧ Q,  prop: ℙ,  infix_ap: x f y,  nat: ℕ,  subtype_rel: A ⊆r B
