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. |
