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.
