摘要
由Sobolev嵌入定理及一些先验估计,当耗散MKdV方程具有整体解时,得到了一个临界指数.并进一步证明了其确定的半群在H2(Ω)上存在整体吸引子.
By using the Sobolev embedding theorem and some priori estimates, the research establishes a critical exponent when the solution exists globally for a dissipative MKdV equation. Furthermore, the global attractor in H2(Ω) for the semigroup is also obtained.
