SAV-based entropy-dissipative schemes for a class of kinetic equations
Shiheng Zhang, Jie Shen, Jingwei Hu
We introduce novel entropy-dissipative numerical schemes for a class of kinetic equations, leveraging the recently introduced scalar auxiliary variable (SAV) approach. Both first a…

Structure preserving schemes for a class of Wasserstein gradient flows
Shiheng Zhang, Jie Shen
We introduce in this paper two time discretization schemes tailored for a range of Wasserstein gradient flows. These schemes are designed to preserve mass, positivity and to be uni…
