Special Riemannian Metrics and Curvature Functionals

On the CR 3-sphere (online participation)

speaker: Paul Yang (Princeton University)

abstract: I will discuss a sphere theorem CR geometry in dimension three. We say a CR structure is universally embeddable if every finite cover is embeddable. Under this assumption, and positive CR Yamabe class it is possible to show such a structure is a quotient of the standard contact structure of the 3-sphere.
