Title：On properties of solutions to fractional and higher order systems
Speaker：Prof. Dai Wei (Beihang University)
Time：Fri., 9:00-10:00 am, Dec.16, 2022
Venue：Tencent Meeting ID：144-653-067 Passcode：221216
Abstract：
In this talk, we introduce some recent results on properties of solutions to fractional and higher order systems. For instance, the classification of solutions to conformally invariant systems with mixed order and exponentially increasing or nonlocal nonlinearity, and the uniform a priori estimates for positive solutions to the n-th order superlinear Lane-Emden system in bounded domains with Navier boundary conditions in R^n (n>=3). This is joint work with Guolin Qin and Leyun Wu.

Title：Why hexagonal shape prevails? A personal perspective
Speaker：Prof. Luo Senping (Jiangxi Normal University)
Time：Fri., 10:00-11:00 am, Dec.16, 2022
Venue：Tencent Meeting ID：144-653-067 Passcode：221216
Abstract：
The hexagonal shape appears almost ubiquitous in nature. However, the mathematical theory to understand hexagonal shape is far from satisfactory. In this talk, I will present my personal understanding on this direction. I show introduce several related mathematical works, then briefly mention a joint work with Prof. Wei, contributing to the understanding of hexagonal shape.
