Research interests

Basically speaking, my research is concerned with  geometric analysis, which is an area closely related to the geometry and partial differential equations.


  Currently, I am doing independent study with David Glickenstein. we focus on forms and bubbles, which is closely linked to the mathematical problems of minimal surfaces. In particular, I am reading Robert Huff's "soap films and Kelvin's curved, truncated octahedron " , the basic idea here is using the Weierstrass representation to parametrize a minimal surfaces, however, the calculation here involving a lot of stuff such as conformal maps in the complex plane, which is not that easy and I need to learn.

In the Fall of 2013, I did my RTG with David Glickenstein.  In this project we investigate the evolution of some graphs under a certain type of flow. Let's see a simple example:


            We see that under this flow, the graph shrinks to a point eventually, and the shape looks like regular as it shrinks to a point. We shall see that this phenomenon happens for the  arbitrary "star" . This is the basic intuition for this  project.  If you are interest or want to know more, please contact  me.
Before 2012, when I was a student at Fudan University, I spent most of my time on study the Poincare conjecture. My master thesis is about the monotonicity of  some operator under a new geometric flow - Ricci Hamonic flow. Similar to the discussion of "no breather" established by Perelman, we define some new energy functions, and discuss their monotonicity and applications.
