In this paper, we prove that positive formula3-curvature for any formula5 implies positive Ricci curvature. Hence a compact locally conformally flat manifold with positive formula3-curvature (formula5) is a space form. And we prove some conformal quermassintegral inequalities, which are analogous to the classical quermassintegral inequalities in convex geometry.
