Rigidity results for the p‐Laplace type equations on compact Riemannian manifolds

Abstract

In this paper, we obtain two rigidity results for ‐Laplace type equation and ‐Laplace equation with exponential nonlinearity on ‐dimensional compact Riemannian manifolds by using of nonlinear flow and the carré du champ methods, respectively, where rigidity means that the PDE has only constant solution when a parameter is in a certain range. Moreover, an interpolation inequality is derived as an application.
