Title: On asymptotic expansions and curvature estimates for 4-dim conformally compact Bach flat manifolds
Abstract: We discuss the effect of the conformal infinity on a 4-dim conformally compact Bach flat manifold with constant scalar curvature. We show the asymptotic expansions of the 4-dim conformally compact Bach flat manifold near the conformal infinity and also give the curvature estimates.
第二个报告：季丹丹（福建师范大学）
Time:15:10~16:10
Title:Some research on isoperimetric surface of asymptotically hyperbolic manifolds
Abstract: In this talk, we will discuss our some joint with Y.G. Shi and B. Zhu. We focuses on the properties of isoperimetric surfaces in asymptotically hyperbolic manifold M with R≥-6 and the geometric relations between isoperimetric surfaces and asymptotically hyperbolic manifold. We prove that the isoperimetric regions with positive lower bounded volumes cannot drift off to the infinity of M provided that the asymptotically hyperbolic manifold M with R≥-6 is not standard hyperbolic space. Besides, we obtain a formula on expansion of isoperimetric profile in terms of renormalized under some conditions.
第三个报告：徐旭（武汉大学）
Time: 16:20~17:20
Title: On the global rigidity of sphere packings on 3-dimensional manifolds
Abstract: In this talk, we will give a proof of the global rigidity of sphere packings on 3-dimensional manifolds, which implies the uniqueness of hyperbolic structure on 4-dimensional manifolds. This is a 3-dimensional analogue of the rigidity in Andreev-Thurston theorem conjectured by Cooper and Rivin. We shall further study the global rigidity of the combinatorial scalar curvature introduced by Ge and the author.
