1 引言带非局部项非线性四阶Kuramoto-Sivashinsky方程(NK-S)方程是数学物理中的重要方程(见(1.1)),它描述了混合气体燃烧过程中火焰是如何随时间演变的。随着无穷维动力系统研究的深入,人们越来越关注方程解的大时间性态.在文[3]中作者研究了这类
We construct half discrete and fully discrete Fourier spectral scheme of this equation , prior estimates and prove the stability of half discrete Fourier spectral scheme.At same time we discuss their error estimate,the existence of approximate attractors and its up continuity.
