报告摘要 报告人 : 殷浩报告题目 :Ricci flow on surfaces with conical singularities 摘要 :In this talk, we will discuss the normalized Ricci flow on surfaces with conical singularities. We will show that under some additional assumptions, the ricci flow converges to a constant curvature metric. 报告人 : 宋翀报告题目 :The KdV curve and Schrodinger-Airy curve 摘要 :In this talk, I will introduce the notion of KdV curves and Schrodinger-Airy curves. These curves are stable solutions to the geometric KdV-Airy flow equation and Schrodinger-Airy flow equation respectively, which are proposed by Sun and Wang recently. We demonstrate that the KdV curves can be regarded as a 3-rd order analogue of geodesics. Other interesting properties and explicit examples of these curves will be addressed. In addition, we will consider a perturbed KdV curve system and show the existence of multiple solutions to this system on torus. 报告人 : 陈立报告题目 :On the Convergence Behavior of Harmonic Map Sequence from Cylinders 摘要 :In this paper, we are concerned with the convergence behavior of a sequence of harmonic maps from long cylinders with uniformly bounded energy. If the bubbling phenomenon does not occur, we give the length formula of the limit map (i.e. geodesic in the target manifold). 报告人 : 江宁报告题目 :Small Deborah number limits of micro-macro polymeric flows 摘要 :In this talk, I will the recent progress of the mathematical theory of the micro-macro polymeric flow, such as FENE ( Finitely Extensible Nonlinear Elastic) model and Oldroyd-B model. They are coupled by macroscopic fluids and microscopic polymers to describe complex fluids. The Deborah numbers measures how the complex fluid behaves like the regular fluid. When the Deborah number is small, we derive an inhomogeneous incompressible Navier-Stokes equations, i.e. the density is non-constant and the viscosity depends on the density. We justified this small Deborah number limits. This is a joint work with Fang-hua, Lin. 报告人 : 葛化彬报告题目 :Combinatorial Ricci Flows on Surfaces 摘要 :In this talk, I will say something about discrete surface Ricci flow introduced by Bennett Chow and Feng Luo. For a triangulated surface, by assigning a positive number to each vertex,which is called circle packing metric, we get a combinatorial Gaussian curvature.then discrete Ricci flow is introduced naturally as a stright forward analogy with che classical Hamilton-Ricci flow. The existence and convergence results about discrete flow will be stated, and then, several interesting questions will be posed. 3
