Abstract
In this paper, we use the Nash–Moser iteration method to study the local and global behaviors of positive solutions to the nonlinear elliptic equation \(\Delta _pv +av^{q}=0\) defined on a complete Riemannian manifolds (M, g) where \(p>1\), a and q are constants and \(\Delta _p(v)=\textrm{div}(|\nabla v|^{p-2}\nabla v)\) is the p-Laplace operator. Under some assumptions on a, p and q, we derive gradient estimates and Liouville type theorems for such positive solutions.
