Günter M. Ziegler, FU Berlin

Time: Wed 2011-10-12 14.30 - 15.30

Location: Oskar Kleins auditorium, AlbaNova, Roslagstullsbacken 21

Program:

13.15-14.00 Precolloquium: for PhD and master students

14.30-15.30 Colloquium talk by Günter M. Ziegler (FU Berlin) "On some partition problems and their configuration spaces"

This lecture will be a report about a research endeavour that started with a seemingly harmless problem about cutting an arbitrary polygon into N pieces of equal area — and led us on a path that connects quite diverse mathematical subjects such as generalized Voronoi domains, optimal transportation, configuration spaces, subspace arrangements, and computations in equivariant cohomology. (Joint work with Pavle V. M. Blagojevic.)

15.30-16.30 Coffee and SMC social get-together
