A Discrete Uniformization Theorem for Polyhedral Surfaces

Feng Luo (Rutgers)

Wednesday 11 May 2016 from 12:00–13:00 in Carslaw 535A

Please join us for lunch after the talk!


Abstract: We introduce a discrete conformality for polyhedral metrics on surfaces. It is shown that each polyhedral metric on a surface is discretely conformal to a constant curvature polyhedral metric which is unique up to scaling. Furthermore, the constant curvature metric can be found by a finite dimensional variational principle. This is joint work with David Gu, Jian Sun and Tianqi Wu.
