Contents
Let $S\subset\mathbb{R}^n$ be a closed unbounded set. We consider nonlinear elliptic partial differential inequalities of the form \[ (-\Delta)^k u \ge a(x)|Du|^q \quad (x\in\mathbb{R}^n\setminus S) \] and \[ -\Delta_p u \ge a(x)|Du|^q \quad (x\in\mathbb{R}^n\setminus S) \] where the coefficient $a(x)$ may have a singularity on the set $S$, and their generalizations. We establish sufficient conditions for nonexistence of solutions to such inequalities in appropriate functional classes extending and improving in a certain sense the results of our paper \cite{1}. \begin{thebibliography}{99} \bibitem{1} E.
