Non-compactness of the Prescribed Q-curvature Problem in Large Dimensions

Abstract

Let $(M,g)$ be a compact Riemannian manifold of dimension $N\ge 5$ and $Q_g$ be its $Q$ curvature. The prescribed $Q$ curvature problem is concerned with finding metric of constant $Q$ curvature in the conformal class of $g$. This amounts to finding a positive solution to \[ P_g (u)= c u^{\frac{N+4}{N-4}}, u>0 {on} M\] where $P_g$ is the Paneitz operator. We show that for dimensions $N\ge 25$, the set of all positive solutions to the prescribed $Q$ curvature problem is {\em non-compact}.
