Efficient Spectral Collocation Method for Tempered Fractional Differential Equations

open access: yesFractal and Fractional, 2023
Transient anomalous diffusion may be modeled by a tempered fractional diffusion equation. In this paper, we present a spectral collocation method with tempered fractional Jacobi functions (TFJFs) as basis functions and obtain an efficient algorithm to ...
