| Abstract: | This paper presents a finite difference method for solving time delay diffusion-wave fractional differential equations, we instead the first order of time by α order (0 < α < 1) Caputo fractional differential derivative in equations. In this paper, the fractional differential is discretized by the Lubich linear multistep method, and the paper uses the segmented interval to prove the stability of the algorithm, and it is validated by numerical experiments. |
