Topological type Fukaya categories and Calabi-Yau/Cluster categories
A Series of Talks in Cluster Theory Speaker: Dr. Yu Qiu (The Chinese University of Hong Kong) (I). Topological type Fukaya categories and Calabi-Yau/Cluster categories. Abstract: We introduce Calabi-Yau-X categories of quivers with superpotential from surfaces and show that their cluster categories are topological Fukaya categories. We also survey various topological type Fukaya...

题目： Rigidity of entire self-shrinking solutions on C^n to the Kahler-Ricci flow报告人： 王文龙（北京大学）时间：5月7日（周一） 10：30-11：30地点： 工商楼4楼报告厅摘要：G. Drugan, P. Lu and Y. Yuan proved that every complete entire self-shrinking solution on C^n to the Kahler-Ricci flow must be flat. I will talk about some new rigidity results without completeness assumption but under real conve...

Onsager’s Variational Principle as an approximation tool in dynamics
题目：Onsager’s Variational Principle as an approximation tool in dynamics 地点：工商楼4楼报告厅 时间：2018年4月27日10:00--11:00 报告人： 邸亚娜研究员 中国科学院数学与系统科学研究院 摘要： Many basic equations describing the dynamics are derived from a variational principle proposed by Onsager in his celebrated paper on the reciprocal relation (1931). This includes Stoke...
