Approximation of Weak Geodesics and Subharmonicity of Mabuchi Energy, II: ε-...The purpose of this talk is to study the strict convexity of the Mabuchi functional along a C1,1-geodesic, with the aid of the ϵ-geodesics. We proved the L2-convergence of the fiberwise volume element of...李龙 助理教授（上海科技大学）腾讯会议室2021年11月29日（星期一） 15:45-17:45

Isometric Immersions from Geometric and PDE PerspectivesWe report our recent work on a classical problem in geometric analysis: isometric immersions and/or embeddings of Riemannian and semi-Riemannian manifolds. The underlying PDE (partial differential equation) is the Gauss--Codazzi--Ricc...李思然 副教授（上海交通大学）腾讯会议室2021年11月29日（星期一） 13:30-14:30

On Critical Hartree Equations: Qualitative Analysis and its ApplicationsIn this talk I will first introduce some qualitative properties of the solutions of the critical Hartree equation, such as the regularity, symmetry, decay estimates, classification and nondegeneracy. Then as an applicati...杨敏波 教授（浙江师范大学）腾讯会议室2021年11月28日（星期日） 14:45-15:45

On Kodaira Dimension of Almost Complex ManifoldsThe Kodaira dimension is a fundamental invariant in complex geometry and algebraic geometry. Recently, it has been introduced to almost complex manifolds and has several applications. In this talk, I will discuss some properties of Kodaira dimension on almost complex manifolds and review some recent results. This talk is mainly based on joint work with Weiyi Zhang.陈豪杰 讲师 （浙江师范大学）腾讯会议室2021年11月26日（星期五） 15:00-16:00

Progress on Restricted Sums of Four SquaresIn 1770 Lagrange established the famous four-square theorem: Each $n\in\mathbb N=\{0,1,2,\ldots\}$ can be written as a sum of four squares. In 2016 the speaker posed many conjectures refining Lagrange's four-square theorem. For example, his 24-conjectu...孙智伟 教授 （南京大学）致远楼101室2021年11月26日（星期五） 10:00-11:00
