摘要:

以研究二维自治g-Navier-Stokes方程解的全局渐近性为目的,用算子分解方法证明了在有界区域上含非线性阻尼的二维自治g-Navier-Stokes方程解的双全局吸引子存在性,并估计了其Hausdorff 维数和Fractal维数。结果表明,该方程解的双全局吸引子存在且具有有限的Hausdorff 维数和有限的分形维数。

关键词: g-Navier-Stokes方程双全局吸引子非线性阻尼    
Abstract:

In this paper, in order to study the global asymptotic properties of solutions of two-dimensional autonomous g-Navier-Stokes equations, the existence of bi-global attractors for g-Navier-Stokes equation with nonlinear dampness on some bounded domains were studied using the method of operator decomposition. The Hausdorff dimension and fractal dimension are estimated. The results show that the bi-global attractor exists and has finite Hausdorff dimension and fractal dimension.

Key words: g-Navier-Stokes equation    bi-global attractors    nonlinear dampness
