Geometry III:
Discrete conformal maps
(Winter 2019)
|
|
This is a course of the
Berlin Mathematical School
held in English (unless all attending BMS students prefer German).
Contents
The course will be on the following topics and what they have to do
with each other:
- Nonlinear theory of discrete conformal maps:
- circle packings and circle
patterns
- discrete conformal equivalence of triangle meshes
- Realization of
hyperpolic polyhedra with prescribed dihedral angles or intrinsic metric.
