proposition: Theorem CombLinear_reducestar : forall (Q : list (poly A0 eqA ltM)) (p q : list (Term A n)), reducestar A A0 A1 eqA invA minusA multA divA eqA_dec n ltM ltM_dec Q p q -> canonical A0 eqA ltM p -> CombLinear Q q -> CombLinear Q p.
proof: Proof. Proof using os cs. intros Q p q H'; elim H'; auto. intros p0 q0 H'0 H'1 H'2 H'3. apply CombLinear_reduceplus with (q := q0); auto. Qed.
