非线性源项为临界指数且阻尼与位移相关的强阻尼wave equations的全局吸引子

Global attractors for strongly damped wave equations with displacement dependent damping and nonlinear source term of critical exponent

Azer Khanmamedov

摘要:

本文研究了三维强阻尼波动方程解的长时间性态。证明了由该方程生成的半群在H_{0} ^{1}(Ω)\times L_{2}(Ω)中具有全局吸引子,并证明了该全局吸引子是H^{2}(Ω)\times H^{2}(Ω)的有界子集,也是H^{2}(Ω)\cap H_{0} ^{1}(Ω)\times H_{0} ^{1}(Ω)中的全局吸引子.

英文摘要:

In this paper the long time behaviour of the solutions of 3-D strongly damped wave equation is studied. It is shown that the semigroup generated by this equation possesses a global attractor in H_{0}^{1}(Ω)\times L_{2}(Ω) and then it is proved that this global attractor is a bounded subset of H^{2}(Ω)\times H^{2}(Ω) and also a global attractor in H^{2}(Ω)\cap H_{0}^{1}(Ω)\times H_{0}^{1}(Ω).
