Some New Entire Solutions to the Fisher-KPP Equation on the Half LineIn this talk I will consider the Fisher-KPP equation on the half line with Dirichlet boundary condition. We will construct some entire solutions for this problem. Each of them has different alpha-limit as the time goes to minus infinity. and can be used to characterize the asymptotic behavior for different initial data.娄本东 教授 (上海师范大学)宁静楼115室2021年7月17日 星期六 15:30-16:30

几何流掠影几何流也叫几何发展方程，是指关于某些几何量的演化方程。按照这些几何量的属性，几何流可以分为内蕴几何流与外蕴几何流。内蕴几何流以Ricci流为代表，外蕴几何流以平均曲率流为代表。我们将简要回顾几何流，特别是Ricci流和平均曲率流的发展历程、当前状况、以及其可能的应用前景。致远楼101室2021年7月8日 星期四 13：30-15：30

Okounkov Bodies and Volume Comparison for Kahler Manifolds with Positive Ricc...In this talk we will show that the volume of compact Kahler manifold with positive Ricci curvature cannot be bigger than the volume of the complex projective space. The proof requires some construction from convex geometry that goes back to Okounkov. The entire argument is purely algebraic and is quite different from the analogous Bishop's sphere theorem in Riemannian geometry.张科伟 讲师 （北京师范大学）腾讯会议室2021年7月8日 8:30-9:30

Stability of a Nonlinear Wave for the Out-Flow Problem of the Navier-Stokes-P...In this talk, we present the asymptotic behavior of the solutions for the out-flow problem to the one-dimensional compressible Navier-Stokes-Poisson equation. First, we construct the nonlinear wave, then we address the large-time behavior of the solution by energy method. This is a joint work with Prof. Peicheng Zhu.黎野平 教授 （南通大学）宁静楼104室2021年7月8日 9:30-10:30

Eigenvalue and Heat Kernel Estimates on the Canonical Bundle of Kaehler Manif...Let M be an m dimensional closed Kaehler manifold. We will present certain eigenvalue and heat kernel estimates for the Hodge Laplacian acting on smooth sections of the canonical bundle of M, i.e., (m,0)-forms. The main results only rely on the bound of the Ricci curvature, and the volume and diameter of M, instead of the bound of the whole curvature tensor for general differential forms.朱萌 教授 （华东师范大学）宁静楼104室2021年7月8日 10:30-11:30

Existence and Uniqueness of Solutions to the Orlicz -Aleksandrov ProblemRecently, an Orlicz Aleksandrov problem has been posed and two existence results of solutions to this problem for symmetric measures have been established. In this talk, we will report the existence and uniqueness of solutions to the Orlicz Aleksandrov problem for non-symmetric measures.冯宜彬 博士后（中国科学技术大学）腾讯会议室2021年7月6日 8:00-9:00

Rigidity Results of CSL Submanifolds in the Unit SphereI will talk about the rigidity of contact stationary Legendrian (CSL) submanifolds in the unit sphere based on the joint works with Prof. Luo Yong and Dr. Yin Jiabin.孙林林 副研究员 （武汉大学）腾讯会议室2021年7月6日 9:00-10:00

Inverse Mean Curvature Flow for Space-Like Graphic Hypersurfaces with Boundar...In this talk, we introduce the evolution of space-like graphic hypersurfaces defined over a convex piece of hyperbolic plane〖 H〗^n (1), of center at origin and radius 1, in the (n+1)-dimensional Lorentz-Minkowski space R_1^(n+1) along the inverse mean curvature flow with the vanishing Neumann boundary condition, and show that this flow exists for all the time.毛井 教授（湖北大学）腾讯会议室2021年7月6日 10:00-11:00
