Finite-Time Stability for nonlinear fractional differential equations with Time Delay

Journal of Donghua University(English Edition) 2022年第5期39卷 446-453页

作者：閤华珍寇春海 College of Science Donghua UniversityShanghai 201620China

The finite-time stability and the finite-time contractive stability of solutions for nonlinear fractional differential equations with bounded delay are investigated. The derivative of Lyapunov function along solutions of the considered system is defined in terms of the Caputo fractional Dini derivative. Based on the Lyapunov-Razumikhin method, several sufficient criteria are established to guarantee the finite-time stability and the finite-time contractive stability of solutions for the related systems. An example is provided to illustrate the effectiveness of the obtained results.

ADI Finite Element Method for 2D nonlinear Time fractional Reaction-Subdiffusion equation

引用

American Journal of Computational Mathematics 2016年第4期6卷 336-356页

作者： Peng Zhu Shenglan Xie Department of Mathematics Jiaxing University Jiaxing China Nanhu College Jiaxing University Jiaxing China

In this paper, an alternating direction Galerkin finite element method is presented for solving 2D time fractional reaction sub-diffusion equation with nonlinear source term. Firstly, one order implicit-explicit method is used for time discretization, then Galerkin finite element method is adopted for spatial discretization and obtain a fully discrete linear system. Secondly, Galerkin alternating direction procedure for the system is derived by adding an extra term. Finally, the stability and convergence of the method are analyzed rigorously. Numerical results confirm the accuracy and efficiency of the proposed method.
