Abstract

On a smooth, closed Riemannian manifold (M,g)(M,g) of dimension n3n\ge3 with positive scalar curvature and not conformally diffeomorphic to the standard sphere, we prove that the only conformal metrics to gg with constant Q-curvature of order 4 are the metrics λg\lambda g with λ>0\lambda>0 constant.
