Title: Embedded Constant Mean Curvature Tori in the Three-Sphere

Abstract: this a joint work with Ben Andrews. The minimal surface
is the surface with constant mean curvature zero. It was conjectured
by H. B. Lawson in 1970s that the only embedded minimal torus in
three-sphere is the Clifford torus. In 1980s, U. Pinkall and
I. Sterling conjectured that embedded tori with CMC in three-sphere
are surfaces of revolution. At March of 2012, Simon Brendle of
Stanford University solved the Lawson conjecture. At April of 2012,
Ben Andrews and Haizhong Li gave a complete classification of CMC
embedded tori in the three-sphere. When the constant mean curvature
is equal to zero or Â±1 / \sqrt{3}, the only embedded torus is the
Clifford torus. For other values of the mean curvature, there exists
embedded torus which is not the Clifford torus, Ben Andrews and
Haizhong Li gave a complete description of such surfaces. As a
Corollary, Ben Andrews and Haizhong Li Theorem have solved the
famous Pinkall-Sterling conjecture.
