abstract:
In this paper we prove non-existence and classification results for elliptic fully nonlinear elliptic degenerate conformal equations on certain subdomains of the sphere with prescribed constant mean curvature along its boundary. We also consider non-degenerate equations. Such subdomains are geodesic balls in ${\Bbb S}^m$, punctured balls and annular domains.
Our results extend those of Escobar when $m\geq 3$, and Hang-Wang and Jim\'{e}nez when $m=2$.
