Noncommutative principal G-bundles 11:10 Fri 14 Sep, 2018 :: Barr Smith South Polygon Lecture theatre :: Keith Hannabuss :: University of Oxford
Noncommutative geometry provides greater flexibility for studying some problems. This seminar will survey some work on noncommutative principal G-bundles. These were classified for abelian groups some years ago, but nonabelian groups require a different approach, using tools developed for a totally different reason in the 1980s. This uncovers links with ergodic theory, quantum groups and the Yang-Baxter equation.
