WebThe main result of [JL2] is that the CR Yamabe problem has a solution on a compact strictly pseudoconvex CR manifold M provided that A(M) < A(S2n+i), where S2n+ is the sphere in n+l . In order to show that most CR manifolds M satisfy A(M) < A(52n+l), it is crucial to identify the extremal contact forms for the Yamabe functional on the sphere.
