Korteweg-de Vries方程一个高阶格式的收敛性

Convergence of a higher-order scheme for Korteweg-de Vries equation

Rajib Dutta, Ujjwal Koley, Nils Henrik Risebro

摘要:

研究了KdV方程Cauchy问题高阶差分格式的收敛性。更准确地说,我们设计了一个Galerkin型隐格式,它在空间上具有更高的精度,在时间上具有一阶精度。对L^2中的初始数据建立了收敛性,并证明了该格式在L^2(0,T; L^2_loc(\R))中强收敛到一个弱解.最后,通过几个例子说明了收敛性。

英文摘要:

We study the convergence of higher order schemes for the Cauchy problem associated to the KdV equation. More precisely, we design a Galerkin type implicit scheme which has higher order accuracy in space and first order accuracy in time. The convergence is established for initial data in L^2, and we show that the scheme converges strongly in L^2(0,T; L^2_loc(\R)) to a weak solution. Finally, the convergence is illustrated by several examples.
