摘要
在R2上具有光滑边界的有界区域Q上考虑了具有线性乘积噪声的随机非自治Ginzburg-Landau方程u/t-(λ+iα)Δu-(ν-σ22)u+(k+iβ)|u|2 u=f(x,t)+σudW dt.我们运用Ball创建的能量方程方法建立了上述方程的拉回渐近紧性,进而证明了在相空间L2(Q)上的拉回吸引子的存在性.
Let Q be an open bounded domain in R2 with sufficiently regular boundary .We consider the following non-autonomous stochastic Ginzburg-Landau equation with multiplicative white noise :?u?t - (λ+ iα)Δu - (ν- σ22 )u+ (k+ iβ)| u|2 u = f (x ,t)+ σu°dWd t . We use the method of energy equations introduced by Ball to establish the pullback asymptotic com-pactness ,and then prove the existence of pullback attractor for the equation above in L2 (Q) .
