High-order nonuniform time-stepping and MBP-preserving linear schemes for the time-fractional Allen-Cahn equation

Bingyin Zhang, Hongfei Fu

In this paper, we present a class of nonuniform time-stepping, high-order linear stabilized schemes that can preserve both the discrete energy stability and maximum-bound principle…

A generalized fractional Laplacian

Xiangcheng Zheng, V. J. Ervin, Hong Wang

In this article we show that the fractional Laplacian in can be factored into a product of the divergence operator, a Riesz potential operator, and the gradient operator. U…
