Lower bounds at infinity for solutions to second order elliptic equations

Abstract

We study lower bounds at infinity for solutions to $$ |Pu|\leq M|x|^{-\delta_1}|\nabla u|+M|x|^{-\delta_{0}}|u| $$ where $P$ is a second order elliptic operator. Our results are of quantitative nature and generalize those obtained in [3,6]. For more information see https://ejde.math.txstate.edu/Volumes/2023/69/abstr.html
