Abstract

In this study, the locally one dimensional (LOD) method is used to solve the two dimensional time fractional diffusion equation. The fractional derivative is the Caputo fractional derivative of order α. The rate of convergence of the finite difference method is presented. It is seen that this method is in agreement with the obtained numerical solutions with acceptable central processing unit time (CPU time). Error estimates, numerical and exact results are tabulated. The graphics of errors are given. MSC 2010: 65M06, 65M22, 34K37

求解二维分数阶扩散方程的一种新的数值格式
本文采用局部一维(LOD)方法求解二维时间分数扩散方程。分数导数是α阶的Caputo分数导数。给出了有限差分法的收敛速度。可以看出,该方法与所获得的具有可接受的中央处理单元时间(CPU时间)的数值解是一致的。误差估计、数值和精确结果制成表格。给出了误差图形。MSC 2010:65m0665m2234k37
