Spectral and spectral element methods for fractional advection–diffusion–reaction equations
-
Anna Lischke
Abstract
We review recent advances in spectral and spectral element methods for a class of fractional partial differential equations. We focus on linear advection- diffusion-reaction equations in one and two dimensions. In particular, we discuss how to deal with boundary and interior singularity of solutions on finite intervals, on the half line, and on two-dimensional domains. Regularity theory for equations with fractional Laplacian is also presented. Finally, we present two approaches to discretize equations with space-time fractional derivatives. Numerical results are presented for both one- and two-dimensional problems.
