On a Dini type blow-up condition for nonlinear higher order differential inequalities

Abstract

We obtain a Dini type blow-up condition for global weak solutions of the differential inequality $$ \sum_{|\alpha| = m} \partial^\alpha a_\alpha (x, u) \ge g (|u|) \quad \mbox{in } {\mathbb R}^n, $$ where $m, n \ge 1$ are integers and $a_\alpha$ and $g$ are some functions.
