Non-stability of Paneitz-Branson equations in arbitrary dimensions

Abstract

Let $(M,g)$ be a compact riemannian manifold of dimension $n\ge 5$. We are interested in the stability of a slighly subcritical Paneitz-Branson type equation on $M$. Assuming that there exists a positive nondegenerate solution of the critical equation and under suitable conditions, we prove that this equation is not stable for all $n\ge 5$.
