研究非线性Burgers型方程=周期问题解的大时间渐近性态,其中Ω=[-π,π],λ< 1。证明了若初值=,则周期问题存在唯一解<$(t,x)∈ C([0,∞); L2(Ω)<$C∞((0,∞)× R).此外,在一些额外的条件下,我们发现解的渐近展开。© 2010 Springer巴塞尔股份公司。
We study large time asymptotic behavior of solutions to the periodic problem for the nonlinear Burgers type equation= where Ω=[-π, π], λ< 1. We prove that if the initial data=, then there exists a unique solution ψ (t, x)∈ C ([0,∞); L 2 (Ω)∩ C∞((0,∞)× R) of the periodic problem. Moreover, under some additional conditions we find the asymptotic expansion for the solutions.© 2010 Springer Basel AG.
