论文给出了二维有界区域上Ladyzhenskaya流体力学方程组的确定模与确定结点的个数估计.结果表明若该方程组的任意两个弱解的前有限个傅立叶模有相同的渐近行为,则这两个解就具有相同的渐近行为;若该方程组的任意两个强解在有限个空间中的点上有相同的渐近行为,则这两个解几乎在整个空间上具有相同的渐近行为. 相似文献

格点系统存在指数吸引子的充分条件及应用 总被引:1,自引:0,他引:1
本文给出了一般格点动力系统存在指数吸引子的充分条件,然后将得到的结果应用到下面的格点非线性Schr(o|¨)dinger方程:iu_m-γ(2u_m-u_(m+1)-u_(m-1))+iκu_m+δ|u_m|~(2σ)u_m=g_m,m∈Z.设γ,κ,δ,σ和g_m满足适当的条件,证明了该格点方程存在指数吸引子. 相似文献
