C Li, A Chen - International Journal of Computer Mathematics, 2018 - Taylor & Francis
In this review paper, we are mainly concerned with the finite difference methods, the
Galerkin finite element methods, and the spectral methods for fractional partial differential …

The AAA algorithm for rational approximation

Y Nakatsukasa, O Sète, LN Trefethen - SIAM Journal on Scientific Computing, 2018 - SIAM
We introduce a new algorithm for approximation by rational functions on a real or complex
set of points, implementable in 40 lines of MATLAB and requiring no user input parameters …

[КНИГА][B] Theory and numerical approximations of fractional integrals and derivatives

C Li, M Cai - 2019 - SIAM
Fractional calculus, which has two main features—singularity and nonlocality from its origin—
means integration and differentiation of any positive real order or even complex order. It has …

Fast evaluation of the Caputo fractional derivative and its applications to fractional diffusion equations

S Jiang, J Zhang, Q Zhang, Z Zhang - … in Computational Physics, 2017 - cambridge.org
The computational work and storage of numerically solving the time fractional PDEs are
generally huge for the traditional direct methods since they require total memory and work …

Radiation boundary conditions for the numerical simulation of waves

T Hagstrom - Acta numerica, 1999 - cambridge.org
