Connected Sum of Spherical CR Manifolds with Positive CR Yamabe Constant

Suppose \(M_{1}\) and \(M_{2}\) are two closed (compact with no boundary) spherical 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 spherical CR structure with positive CR Yamabe constant.
