摘要:

本文给出了扩张圆上Kuramoto-Sivashinsky方程的Crank-Nicolson差分有限差分法(\cite{KUY}),并证明了该格式的存在唯一性和二阶误差估计.该方程可以作为一个扰动方程从圆解的界面方程,可以提供指导,了解波数选择的界面方程的解决方案。我们提出的数值方案可以帮助这样的数学分析。

英文摘要:

This paper presents a finite difference method combined with the Crank--Nicolson scheme of the Kuramoto--Sivashinsky equation defined on an expanding circle (\cite{KUY}), and the existence, uniqueness, and second-order error estimate of the scheme. The equation can be obtained as a perturbation equation from the circle solution to an interfacial equation and can provide guidelines for understanding the wavenumber selection of solutions to the interfacial equation. Our proposed numerical scheme can help with such a mathematical analysis.
