On global solutions of quasilinear second-order elliptic inequalities
A. A. Kon'kov, A. E. Shishkov
We consider the inequality $$ - \operatorname{div} A (x, \nabla u) \ge f (u) \quad \mbox{in } {\mathbb R}^n, $$ where and is a Caratheodory function such that $$ C_1…
On a Dini type blow-up condition for nonlinear higher order differential inequalities
A. A. Kon'kov, A. E. Shishkov
We obtain a Dini type blow-up condition for global weak solutions of the differential inequality $$ \sum_{|α| = m} \partial^α a_α(x, u) \ge g (|u|) \quad \mbox{in } {\mathbb R}^n,…
On the behavior of Kneser solutions of nonlinear ordinary differential equations
Andrej A. Kon'kov
We obtain priory estimates and sufficient conditions for Kneser solutions of ordinary differential equations to vanish in a neighborhood of infinity
On properties of solutions of quasilinear second-order elliptic inequalities
Andrej A. Kon'kov
Let be an unbounded open subset of , , and be a function such that $$ C_1 |ζ|^p \le ζ A (x, ζ), \quad |A (…
On comparison theorems for elliptic inequalities
Andrej A. Kon'kov
We obtain comparison theorems for non-negative solutions of quasilinear elliptic inequalities
