Title： Some progress on semilinear elliptic inequalities involving gradient terms on weighted graphs

Abstract： We study existence and nonexistence of nontrivial positive solutions to the following semilinear elliptic inequalities involving gradient terms on weighted graphs $$\Delta u+u^p|\nabla u|^q\leq 0,$$ Where $(p, q)\in \mathbb{R}^2$. This talk is based on joint works with Qingsong Gu, Lu Hao, Xueping Huang.
