Winter School and Workshop on Polytopes 2025

Osnabrück, February 24 – 28, 2025

The event consists of a 2-day winter school (February 24 and 25) and a 3-day workshop (February 26 – 28). The school consists of three minicourses (three hours each) on general polytopes, lattice polytopes and probabilistic aspects of polytopes. The workshop consists of six invited one-hour talks as well as nine 25-minutes talks and a poster session. You can apply for these talks when registering for the workshop.
