数学与大数据学院邀请鲍灵格林州立大学谢向东教授作线上学术报告

       12月3日上午，数学与大数据学院邀请鲍灵格林州立大学(Bowling Green State University)的谢向东教授作线上学术报告。谢向东教授利用腾讯会议(ID：404-480-951)作了题为“Rigidity and flexibility of maps between Carnot groups”的学术报告。周青山博士主持报告会，学院戎海武院长以及校内外多位教师与学生参会。

       本次报告主要内容是Carnot群上映射的刚性和灵活性。谢向东教授首先介绍了与Carnot群有关的基本定义和一些简单的Carnot群的例子；然后介绍了Carnot群产生的背景，并介绍了一些经典结果；最后介绍了Carnot群上几类映射的刚性和灵活性。整个报告在活跃的气氛中进行，与会的老师同学在报告的过程中提出很多问题，谢教授都耐心的一一解答。报告结束后，谢教授与师生们进行了热烈的讨论与交流。谢教授的报告深入浅出，与会师生受益良多，学术讲座在热烈的掌声中圆满结束。
