Influence of variable coefficients on global existence of solutions of semilinear heat equations with nonlinear boundary conditions

Alexander Gladkov, Mohammed Guedda

We consider semilinear parabolic equations with nonlinear boundary conditions. We give conditions which guarantee global existence of solutions as well as blow-up in finite time of…

Nonexistence of nonnegative entire solutions of semilinear elliptic systems

Alexander Gladkov, Sergey Sergeenko

We consider the second order semilinear elliptic system $Δ u = p (x) v^{α},$ $Δ v = q (x) u^{β},$ where $x \in R^{N},$ $N \geq 3,$ $α$ and $β$ are positive cons…
