A Fast Adaptive Method with a Sum-of-Exponentials Approximation for Fractional Derivative Diffusion Equation

The high numerical computing cost of time-fractional diffusion equation (tFDE) models over long time periods is a major obstacle to their real-world applications. Therefore, this study presents a rapid adaptive finite difference method, which uses the sum-of-exponentials (SOE) technique to quickly e...
