Georgios E. Zouraris

摘要:

考虑矩形区域上半线性二维热方程的初边值问题和Dirichlet边值问题.该问题采用C. Besse(C. R. Acad. Sci.巴黎先生I,vol.326(1998))的非线性薛定谔方程和空间中的标准二阶有限差分法。所提出的方法是无条件适定的,其收敛性是通过证明一个最佳的二阶误差估计,允许一个温和的网格条件。

英文摘要:

We consider an initial and Dirichlet boundary value problem for a semilinear, two dimensional heat equation over a rectangular domain. The problem is discretized in time by a version of the Relaxation Scheme proposed by C. Besse (C. R. Acad. Sci. Paris Sér. I, vol. 326 (1998)) for the nonlinear Schrödinger equation and in space by a standard second order finite difference method. The proposed method is unconditionally well-posed and its convergence is established by proving an optimal second order error estimate allowing a mild mesh condition to hold.
