Geometry III (Winter 2021/2022)

Discrete differential geometry: Discrete confocal quadrics and related topics

We study (smooth and discrete) confocal quadrics and the corresponding confocal coordinate systems. Focussing on this basic example we discuss (smooth and discrete) orthogonal coordinate systems, special parametrizations on surfaces, elliptic fuctions and possibly some of the following related topics: classification of pencils of quadrics, parametrization of quadric intersection curves by elliptic functions, checkerboard incircular nets.

This is an advanced course of the Berlin Mathematical School (BMS) and will be held in English.
