This paper deals with singular/degenerate semilinear critical equations which arise as the Euler-Lagrange equation of Caffarelli-Kohn-Nirenberg inequalities in Rd[jls-end-space/], with d≥2[jls-end-space/].

Abstract

This paper deals with singular/degenerate semilinear critical equations which arise as the Euler-Lagrange equation of Caffarelli-Kohn-Nirenberg inequalities in Rd[jls-end-space/], with d≥2[jls-end-space/]. We prove several rigidity results for positive solutions, in particular we classify solutions with possibly infinite energy when the intrinsic dimension n satisfies 2<4[jls-end-space/].
