This article introduces a new high-order explicit group iterative scheme for solving the two-dimensional time fractional cable equation, showing stability and convergence with numerical examples to demonstrate accuracy and efficiency.
In this article, a new high-order explicit group iterative scheme is developed for the solution of the two-dimensional time fractional cable equation. The proposed scheme is derived from the Crank-Nicolson (C-N) high-order compact finite difference method, where the Caputo discretization and C-N high-order approximations are used for the time fractional and space derivative respectively. The stability and convergence of the proposed scheme are also established. Finally, two numerical examples are presented to show the accuracy and efficiency of the scheme. (C) 2021 THE AUTHORS.
