Niklas C. Affolter
I am a research assistent at the Technical University Berlin,
at the Department of Geometry and Mathematical Physics,
working under the supervision of Boris Springborn.
I'm organizing the X-Student Research Group Combinatorial solutions to discrete integrable systems in the WS22/23. It's an opportunity for students to do their own math research, combining problems from different areas of math.
I spent half a year at ENS Paris (01.03. - 01.09.2022) in the group of
Dmitry Chelkak, but now I'm back!
I coorganized the Discrete Geometric Structures workshop 2022, which was great fun.
Research
Fields of interest:
Geometry, discrete differential geometry, discrete
integrable systems, applications of pure geometry, discrete statistical physics, combinatorics, cluster algebras, circle patterns, discrete conformal theory
