Nuprl Lemma : fpf-disjoint-compatible

[A:Type]. ∀[eq:EqDecider(A)]. ∀[B:A ─→ Type]. ∀[f,g:a:A fp-> B[a]].  || supposing l_disjoint(A;fst(f);fst(g))


Proof




Definitions occuring in Statement :  fpf-compatible: || g fpf: a:A fp-> B[a] deq: EqDecider(T) l_disjoint: l_disjoint(T;l1;l2) uimplies: supposing a uall: [x:A]. B[x] so_apply: x[s] pi1: fst(t) function: x:A ─→ B[x] universe: Type
