Abstract
On a smooth, closed Einstein manifold (M, g) of dimension \(n \ge 3\) with positive scalar curvature and not conformally diffeomorphic to the standard sphere, we prove that the only conformal metrics to g with constant Q-curvature of order 4 are the metrics \(\lambda \)g with \(\lambda > 0\) constant.
