讨论班简介 / About
本讨论班聚焦于偏微分方程(PDE)的数学分析与数值方法,特别关注其与复杂系统研究中的若干核心课题的交叉:
- 界面动力学与相场模型(Allen–Cahn、Cahn–Hilliard、phase-field、crystal growth)
- 不可压缩流体与表面准地转方程(Euler、Navier–Stokes、SQG)
- 自由边界问题与隐式边界值问题(oxygen diffusion、Stefan-type)
- 分数阶与非局域算子(fractional Laplacian、Oldroyd-B、Oldroyd-type)
- 色散与波动方程(Klein–Gordon–Zakharov、quasilinear wave)
- 高维 PDE 的 AI 求解方法(PINN、neural ODE、deep BSDE、Besov-based IBP)
This seminar focuses on the mathematical analysis and numerical methods for PDEs, with particular emphasis on their interactions with several core topics in complex systems research:
- Interface dynamics and phase-field models (Allen–Cahn, Cahn–Hilliard, phase-field, crystal growth)
- Incompressible fluids and surface quasi-geostrophic equations (Euler, Navier–Stokes, SQG)
- Free boundary and implicit boundary value problems (oxygen diffusion, Stefan-type)
- Fractional and nonlocal operators (fractional Laplacian, Oldroyd-B, Oldroyd-type)
- Dispersive and wave equations (Klein–Gordon–Zakharov, quasilinear wave)
- AI methods for high-dimensional PDEs (PINN, neural ODE, deep BSDE, Besov-based IBP)

Congratulations to seminar members, Z. Luo, J. Song, C. Wang, J. Wang, Z. He, C. Yuan for recent (2026) publications in J. Diff. Eq., J. Diff. Eq., J. Math. Phys., Acta Mathematica Scientia, J. Math. Fluid. Mech. and Adv. Math.!
“Remember to sleep; remember to eat (healthily); try to exercise at least three times a week; make sure what you are studying is (mostly) interesting to you and has some challenge.” — Brian Wetton
讨论班不是负担,而是一次次与同行的对话。希望每位参与者都能在报告的严密性、讨论的自由度与研究的乐趣之间找到自己的节奏。
This seminar is not a burden — it is a series of conversations with peers. We hope every participant finds a balance between rigor of presentation, freedom of discussion, and the joy of research.
