Welcome to Bo's webpage!

Recently I am interested in bisectional curvature and holomorphic sectional curvature in complex geometry, and their connections to Ricci flow and other subjects. Here is my profile on mathscinet.


I left Cornell and joined in XMU in 07/2017.

Activities at XMU (2017-)

  • The Geometric Analysis Seminar. This is a weekly seminar at Xiamen University. The seminar covers various topics on differential geometry and related areas. Here is the schedule.

  • "Perspectives in Algebraic and Complex Geometry". This is a mini-workshop at Xiamen University from Jan 19th to Jan 21st in 2018. Here is the schedule.

  • A reading seminar on complex geometry. An informal seminar at Xiamen University since 2018. Here is the schedule.

  • "2018 Conference on Riemann-Finsler Geometry and Related Topics". A conference at XMU from 07/12/2018 to 07/14/2018. Here is the webpage.

  • "Algebraic Surfaces and Related Topics". A workshop at XMU from 09/24/2018 to 09/28/2018. Here is the webpage.
