摘要
研究了带有加法噪音的非自治随机阻尼Sine-Gordon方程组解的渐进行为.运用一致估计证明了D-吸收集的存在性,并由解的分解技巧证明了该动力系统是渐进紧的,从而证明了Sine-Gordon方程组的D-拉回吸引子的存在性.
The asymptotic behavior of the solution to the stochastic damped Sine-Gordon system with additive noise is investigated.Using the Gronwall lemma and the Sobolev embedding theorem,we find that there exists a compact absorption set in the system,which proves the existence of the D-pullback attractor in the Sine-Gordon system.
