地点:理学研究所大楼509.

1.演讲人: 中山大学李长征教授

时间:5月26号上午9:00-12:00.

Title:Introduction to Schubert Calculus

Abstract:In this talk, we will give a brief introduction to Schubert calculus at various levels. We will mainly discuss enumerative problems on complex Grassmannians. We will also talk about Gamma conjecture I for Grassmannian, which is related with the irrationality of Zeta function.


2.演讲人: 浙江大学刘东文研究员

时间:5月26号下午13:30-16:30

Title:  On the local descent of real unitary groups

Abstract:In this talk we first explain the the local Gan-Gross-Prasad conjecture. Assuming this conjecture, we describe the descent of representations of real unitary groups with generic L-parameters. This talk is based on a project joint with Dihua Jiang and Lei Zhang.


3.演讲人:山东大学赵立璐教授

时间: 5月27号上午8:30-11:30.

题目:十个变量的三次型

摘要:1983年,Heath-Brown得到了关于非奇异(non-singular)三次型零点个数的一个渐近公式。报告中,我们将重点讨论这篇文章的技术背景。特别,我们将讨论,这篇文章中的圆法形式和相关课题中的圆法的区别,优势以及可发展的地方。


4. 演讲人:天津大学应用数学中心余讯教授

时间:5月27号下午13:00-16:00.

Title:K3 surfaces, elliptic fibrations and Salem numbers

Abstract: In this talk, we will introduce K3 surfaces and discuss close relations between entropy of automorphisms of K3 surfaces and elliptic fibrations. As an application, we will show that any supersingular K3 surface in odd characteristic has an automorphism the entropy of which is the natural logarithm of a Salem number of degree 22. In particular, such automorphisms are not geometrically liftable to characteristic 0.
