An overview of Hadwiger's conjecture and its variantsOberseminar Discrete Optimization

by Raphael Steiner (ETH Zürich)

Monday Apr 27, 2026, 6:15 PM → 7:15 PM Europe/Berlin

Arithmeum, Lennéstr., 2 - Seminarraum (Arithmeum / Research Institute for Discrete Mathematics)

In this talk I will give a short survey on my favourite open problem in combinatorics, Hadwiger's conjecture from 1943.

I will do my best to give a brief overview of the landmark partial results, including both positive and negative evidences for the conjecture, and sketch some of my own recent results obtained together with various collaborators.

 

The Oberseminar takes place in the Seminarraum, 1st floor. Participants are invited to have coffee or tea in the lounge before.
