Constant Q-curvature metrics with Delaunay ends: the nondegenerate case

João Henrique Andrade, Rayssa Caju, João Marcos do Ó +2

We construct a one-parameter family of solutions to the positive singular Q-curvature problem on compact nondegenerate manifolds of dimension bigger than four with finitely many pu…

Compactness within the space of complete, constant Q-curvature metrics on the sphere with isolated singularities

João Henrique Andrade, João Marcos do Ó, Jesse Ratzkin

In this paper we consider the moduli space of complete, conformally flat metrics on a sphere with k punctures having constant positive Q-curvature and positive scalar curvature. Pr…
