proposition: Theorem minuspf_inv3a_eq : forall (a b : Term A n) (p q : list (Term A n)), eqT a b -> zeroP (A:=A) A0 eqA (n:=n) (minusTerm (A:=A) minusA (n:=n) a b) -> minuspf p q = minuspf (pX a p) (pX b q).
proof: Proof. Proof using os. intros a b p q H' Z; try assumption. rewrite (minusP_inv3a a b p q (minuspf (pX a p) (pX b q))); auto. Qed.
