proposition: Lemma RInt_gen_ext_eq : forall {V : CompleteNormedModule R_AbsRing} {Fa Fb : (R -> Prop) -> Prop} {FFa : ProperFilter Fa} {FFb : ProperFilter Fb} (f g : R -> V), (forall x, f x = g x) -> RInt_gen f Fa Fb = RInt_gen g Fa Fb.
proof: Proof. intros V Fa Fb FFa FFb f g Heq. apply (RInt_gen_ext f g). apply filter_forall. now intros uv x _. Qed.
