Two kinds of numerical algorithms for ultra-slow diffusion equations
Min Cai, Changpin Li, Yu Wang
In this article, two kinds of numerical algorithms are derived for the ultra-slow (or superslow) diffusion equation in one and two space dimensions, where the ultra-slow diffusion…

John-Nirenberg inequalities for noncommutative column BMO and Lipschitz martingales
Guixiang Hong, Congbian Ma, Yu Wang
In this paper, we continue the study of John-Nirenberg theorems for BMO/Lipschitz spaces in the noncommutative martingale setting. As conjectured from the classical case, a desired…
