题目: 非正规算子类与量子非局域性

14:00-14:40

摘要: Banach空间算子与算子类理论是泛函分析的重要内容, 并且与矩阵分析, 量子信息理论等具有广泛而密切的联系. 主要介绍Furuta型算子不等式,亚正规算子, 仿正规算子以及量子非局域性等方面的研究进展.

题目:A note of numerical scheme to stochastic differential equations

14:40-15:20

摘要:The classic Euler-Maruyama (EM) scheme is divergent for stochastic differential equations with Irregular coefficients. In this talk, we will introduce several novel techniques, which could lead to the recovery of the convergence result with a much slower convergence rate. To make this talk self-contained, a brief review of existing results will be given upfront.

题目:The spectra of signed graphs

15:20-16:00

摘要:A signed graph consists of an unsigned graph and a sign function. In this talk, we will introduce some results on the spectra of signed graphs, such as analogue to  signed graphs with exactly two distinct adjacency or Laplacian eigenvaules,integral signed graphs with degree at most 3, signed graphs with extremal energy and Brouwer's conjecture.
