Abstract: 

It is well known that scalar curvature plays a fundamental role in general relativity. As its analogue, conformally variational Riemannian invariants (CVIs) is a category of fundamental scalar-type curvatures which shares many excellent properties in both conformal and Riemannian geometry. In this talk, I will give a brief introduction about our working frame about CVIs and present some interesting results about the geometric and analytic theory about CVIs. Hopefully, these theories can be helpful in the development of general relativity and other fields of mathematical physics. This talk is based on a series of work joint with Jeffrey S. Case from Penn State University and Yueh-Ju Lin from Wichita State University.


Speaker:

袁伟博士,中山大学副教授。2008年本科毕业于南开大学,2010年于中国科学技术大学取得理学硕士学位后赴加州大学圣克鲁斯分校(UC Santa Cruz)学习并于2015年取得理学博士学位。主要研究方向为几何分析和广义相对论。此前曾赴法国巴黎第六大学/庞加莱研究所(IHP)、奥地利维也纳大学/薛定谔研究所(ESI)、韩国高等研究院(KIAS)等多地进行学术访问。

目前已在Mathematische Annalen, Transactions of AMS, Advances in Mathematics, Calculus of Variations and PDE, Analysis and PDE等学术期刊上发表研究论文十余篇。主要包括Brown-York型质量、数量曲率的体积比较定理、特征值估计等的研究,以及同合作者加州大学圣克鲁斯分校的庆杰教授对真空静态时空的研究、同美国威奇塔州立大学的林悦如教授以及宾夕法尼亚州立大学的Jeffery S. Case教授有关Q-曲率及一般黎曼不变量形变中的一些几何分析问题等多个方面的研究工作。
