学术报告1

报告题目:Commutants of composition operators on Fock space

人: 王茂发教授(武汉大学)

报告时间:2025年10月25日上午8:20-9:00

报告地点:数学楼301房间

   要:This talk is devoted to profound and comprehensive characterization on commutants of composition operators on Fock space of several variables.  In addition, we consider the asymptotic behaviour of discrete or continuous semigroups of such operators.


报告人简介:王茂发,武汉大学数学与统计学院教授、博士生导师,主要研究领域为泛函分析及其应用, 特别在函数空间上的算子理论方面取得系列突出成果,先后主持国家自然科学项目多项,在 J Funct Anal, J Operator Theory, Sci China Math等国内外知名期刊上发表学术论文一百余篇。


学术报告2

报告题目:Maps shrinking the joint spectrum or joint numerical range of projections

人: 吴文明教授(重庆师范大学)

报告时间:2025年10月25日上午9:20-10:00

报告地点:数学楼301房间

  要:In this talk, we will discuss the surjective maps which shrink the joint spectrum or joint numerical range of projections.


报告人简介:吴文明,教授,博士生导师,研究方向:算子代数、泛函分析;重庆市巴渝学者特聘教授、重庆市学术技术带头人;先后主持国家项目3项、省部级项目6项,在J. Funct. Anal.、J. Oper. Theo.、Studia Math.、Bull. Lond. Math. Soc.,Sci. China Math.等知名期刊发表论文近30篇。


学术报告3

报告题目:  Weighted Inequalities of Bergman-type Operators

人:王子鹏副教授

报告时间:2025年10月25日上午10:20-11:00

报告地点:数学楼301房间

   :  Bergman-type operators naturally arise from operator theory on analytic function spaces and singular integral operators in modern harmonic analysis. In this talk, we will first give a short review of basic ideas about these operators, then share our recent work on the weighted theory of Bergman-type operators. This is a joint work with Kunyu Guo and Kenan Zhang.


报告人简介:王子鹏,重庆大学数学系副教授,主要从事函数空间上算子论及其相关的调和分析与随机分析的研究。详细研究情况,可参见 //math.unicorn365.cn/staff/detail?userId=367。

学术报告4

报告题目:Rigidity for geometric ideals in uniform Roe algebras

人:蒋报捷博士

报告时间:2025年10月25日上午11:00-11:40

报告地点:数学楼301房间

   要:The rigidity problem for Roe algebras was initially studied by\v{S}pakula and Willett in 2013 and has been completely solved in 2022. In this talk, we will investigate the rigidity problems for geometric ideals in uniform Roe algebras associated to discrete metric spaces of bounded geometry.  Our main result is that if two geometric ideals in uniform Roe algebras are stably isomorphic, then the coarse spaces associated to these ideals are coarsely equivalent.  This presentation is based on a joint work with Jiawen Zhang.


报告人简介:蒋报捷,2018年毕业于复旦大学数学院, 现为重庆师范大学国产自拍 讲师。研究方向为算子代数与非交换几何,相关成果发表在Commun. Math. Phys., J. Funct. Anal., J. Noncommut. Geom.等期刊上。
