Martin Winter, PhD
winter@math.tu-berlin.de
I am a mathematician. I am Dirichlet fellow at TU Berlin and guest researcher at the Max-Planck-Institute for Mathematics in the Sciences in Leipzig. I am researching in discrete geometry, real algebraic geometry, geometric constraint systems, semi-definite optimization, spectral graph theory, algebraic combinatorics and low-dimensional topology. Most recently I am studying the Wachspress Geometry of convex polytopes. I am also working on the formalization of polytope theory in Lean.
I am principal investigator in the priority program “Combinatorial Synergies” and my project is “Wachspress Coordinates - a Bridge between Algebra, Geometry and Combinatorics”.
Before, I was postdoc at the University of Warwick (UK). I got my PhD from TU Chemnitz (Germany) in 2021.
What’s new
- I was visiting ICERM March 10 – 21 during the special semester on “Geometry of Materials, Packings and Rigid Frameworks” and the workshop “Matroids, Rigidity, and Algebraic Statistics”.
- on March 14 I spoke in their seminar about “Progress on the stress-flex conjecture for coned polytope frameworks” (joined work with Roman Prosanov and Ivan Izmestiev)
- on March 18 I gave a Lighting Talk titled “The prestress stability surface of a convex polytope” (joined work with Matthias Himmelmann)
What’s coming
- On April 24 I am speaking in the Nonlinear algebra seminar at MPI Leipzig.
- I will visit the University of Kassel June 10 – 11, 2025 and will speak in their Oberseminar on June 10.
