Optimal convergence of local discontinuous Galerkin methods for convection-diffusion equations

Wenjie Liu, Ruiyi Xie, Li-Lian Wang +1

The local discontinuous Galerkin (LDG) method proposed by Castillo et al. [Math. Comp.,~71 (238): 455-478, 2002] has been shown to be an efficient approach for solving convect…

Optimal error estimates for Legendre expansions of singular functions with fractional derivatives of bounded variation

Wenjie Liu, Li-Lian Wang, Boying Wu

We present a new fractional Taylor formula for singular functions whose Caputo fractional derivatives are of bounded variation. It bridges and ``interpolates" the usual Taylor form…

A Generalized-Jacobi-Function Spectral Method for Space-Time Fractional Reaction-Diffusion Equations with Viscosity Terms

Zhe Yu, Boying Wu, Jiebao Sun +1

In this work, we study a new spectral Petrov-Galerkin approximation of space-time fractional reaction-diffusion equations with viscosity terms built by Riemann-Liouville fractional…

Uniform bounds and asymptotics of Generalized Gegenbauer functions of fractional degree

Wenjie Liu, Li-Lian Wang

The generalised Gegenbauer functions of fractional degree (GGF-Fs), denoted by (right GGF-Fs) and (left GGF-Fs) with $λ>-…

Optimal error estimates for Chebyshev approximations of functions with limited regularity in fractional Sobolev-type spaces

Wenjie Liu, Li-Lian Wang, Huiyuan Li

In this paper, we introduce a new theoretical framework built upon fractional Sobolev-type spaces involving Riemann-Liouville (RL) fractional integrals/derivatives, which is natura…
