In this talk we extend Escobar's classification result [E] to elliptic fully nonlinear conformal equations on certain subdomains of the sphere with prescribed constant mean curvature on its boundary. Such subdomains are the hemisphere with prescribed constant mean curvature on its boundary, and annular domains with minimal boundary. This is joint work with Jose Espinar (IMPA).
