报告题目: Equation   in the plane.

报告摘要： It will be explained how to use the theory of meromorphic functions
to prove several properties of solutions of this equation. In particular a sketch of the proof of
"diameter conjecture" will be given: the minimum diameter of the metric e^{2u}|dz| in
the plane is \pi, and all solutions for which this minimum is attained will be described.
