报告摘要: I will describe several results related to the multiplicity of constant Q-curvature in conformal classes. We develop a general criterion, including in particular a wide range of manifolds. Several striking phenomena occur and in particular we prove existence through geometric bifurcations of constant Q-curvature metrics within the uniqueness class of yamabe metrics
