Abstract: | ![]() In this article,we prove the existence of global solutions for a class of nonlinear evolution equations in H10(Ω)×H10(Ω).Moreover we study the long-time behavior of the solutions.It is proved that under the natural assumptions,these equations possess the compact attractors,where the nonlinear term f satisfies a critical exponential growth condition. |

Keywords: | Nonlinear evolution equation Global solutions Global attractor Critical exponential |
