A Fast O(N log N) Finite Difference Method for the One-Dimensional Space-Fractional Diffusion Equation
This paper proposes an approach for the space-fractional diffusion equation in one dimension. Since fractional differential operators are non-local, two main difficulties arise after discretization and solving using Gaussian elimination: how to handle the memory requirement of O(N2) for storing the...
