Geometry II: Discrete Differential Geometry (Summer 2017)

Lectures Alexander Bobenko Mon 12-14 MA 751
Thu 12-14 MA 848
Tutorials Jan Techter Mon 14-16 MA 848

Contents

Discrete differential geometry takes the concepts and results from the theory of smooth curves and surfaces, and looks for analogs for discrete (polygonal) curves paths) and discrete (polyhedral) surfaces. Rather unexpectedly, the very basic structures of discrete differential geometry turn out to be related to the theory of integrable systms. A list of topics for the course includes: polyhedral surfaces, intelligent (property preserving) discretizations, quad-surfaces, multi-dimensional nets, orthogonal nets, discrete conformal structure and parametrization, integrable systems, examples in physics and geometry, in particular in projective, Lie, Möbius, Laguerre geometries.

This is a course of the Berlin Mathematical School held in english or deutsch (depending on the audience).
