Connected sum CR manifolds CR Yamabe constant Tanaka-Webster scalar curvature Geometry and Topology
Suppose M 1 and M 2 are 3-dimensional closed (compact without boundary) CR manifolds with positive CR Yamabe constant. In this note, we show that the connected sum of M 1 and M 2 also admits a CR structure with positive CR Yamabe constant.
