分析了带全局吸引子的广义Kuramoto-Sivashinsky方程的有限差分格式所生成的离散动力系统的动力性质,在自治系统中得到了有限差分格式的稳定性证明和差分解的误差估计,以及该系统在Hh2空间中全局吸引子的存在性。
The dynamical properties of a class of discrete dynamical systems, generated by finite difference scheme of a generalized Kuramoto - Sivashinsky equation possessing a global attractor, are analyzed. The stability of the difference scheme, the error estimate of the difference solution and the existence of an absorbing set in space H^2h are obtained in autonomouse systems.
