On the higher order conformal covariant operators on the sphere

Research output: Contribution to journalArticle

Abstract

We will show that in the conformal class of the standard metric gs n on Sn, the scaling invariant functional (μg(Sn)) 2m-n/nSnQ2m, gg maximizes at gsn when n is odd and m = n-1/2 or n+3/2. For n odd and m ≥ n+5/2, gsn is not stable and the functional has no local maximizer. Here Q2m,g is the 2mth order Q-curvature.
