Fast solution algorithms for exponentially tempered fractional diffusion equations

Abstract: In this article, a fast‐iterative method and a fast‐direct method is proposed for solving one‐dimensional and two‐dimensional tempered fractional diffusion equations with constant coefficients. The proposed iterative method is accelerated by circulant preconditioning which is shown to converge superlinearly while the proposed direct method is based on circulant and skew‐circulant representation for Toeplitz matrix inversion. In one‐dimensional case, the operation cost of the proposed methods are both shown to … Show more

“…To address this problem, Wang et al [9] proposed a circulant preconditioned generalized minimal residual method (PGMRES) to solve the discretized linear system, whose computational cost is of O(N log N ). Lei et al [23] proposed fast solution algorithms for solving TFDEs in one-dimensional (1D) and two-dimensional (2D). In their article, for 1D case, a circulant preconditioned iterative method and a fast-direct method are developed, and the computational complexity of both methods are O(N log N ) in each time step.…”
