Braids, Associators, and Quantization of Moduli Spaces
Kolloquium

Referent: Dr. Pavol Severa, Univ. Genf
Veranstalter: Catherine Meusburger
Raum: Hörsaal H13

Many interesting non-commutative algebras, especially those that are deformations of commutative ones, can be constructed via braids. I will illustrate this idea in the case of deformations of Poisson-Lie groups (or Lie bialgebras) to non-commutative Hopf algebras, and more generally, in the case of deformation quantization of moduli spaces of flat connections on surfaces with decorated boundary.
