An introduction to complex hyperbolic geometry
马继明 副教授(复旦大学)
2023年5月25日、6月1日 13:00-14:00  闵行校区数学楼401

*主持人:邹燕清 青年研究员

*讲座内容简介:
The theory of complex hyperbolic geometry is still in its childhood, but promises to grow into a rich subfield of geometry.In these talks, I will first talk about the simplest kinds of complex hyperbolic discrete groups, i.e, the deformations of reflection triangle groups in $PU(2,1)$. I will talk about the conjectural picture of Schwartz on these still mysterious subject of complex hyperbolic deformations. If times permits, I will also talk about that some of extra deformations of complex hyperbolic triangle groups give examples complex hyperbolic lattices, these will involve in Ford domains, Dirichlet domains and Jorgensen inequality.
