Multiplicity of conformal metrics with constant Q-curvature

speaker: Yannick Sire (John Hopkins University)

abstract: I will describe a series of multiplicity results for the Q-curvature equation. We develop geometric bifurcation and perturbative techniques to prove the occurrence of bifurcation times when one searches for metrics of constant positive Q-curvature. We obtain several results in various geometric settings like homogeneous spaces, non compact product manifolds or spherical domains.
