XXXIX Workshop on Geometric Methods in Physics 19.06–25.06.2022
XI School on Geometry and Physics 27.06–1.07.2022
In order to secure the right conditions for our Workshop we have decided to exceptionally move (only for this year's meeting) the site of our Workshop to the campus of our University in Białystok.

Cheeger-Simons differential character-valued momentum maps and applications


In order to address Donaldson's topological obstructions for the existence of momentum maps for certain diffeomorphism and gauge groups, an extension of the classical momentum map is introduced, capable to store discrete topological information. This talk will explain how this momentum map was introduced based on the model of the momentum map for Poisson Lie group actions and will discuss some of its applications.
