OAS - Operator algebras: subfactors and their applications The WZW model in physics naturally leads to a study of twisted K-theory for compact Lie groups, which has been studied by Moore-Maldacena-Seiberg, Hopkins, Braun, and Douglas. We re-examine a few aspects of this subject. For example, what is the map on H^3 induced by a covering of compact simple Lie groups? The result is complicated and quite surprising. Also, what can we learn about twisted K-theory from the connection between Langlands duality and T-duality, studied by Daenzer-Van Erp and Bunke-Nikolaus? Again, the result is rather surprising. This is joint work with Mathai Varghese. This talk is part of the Isaac Newton Institute Seminar Series series. ## This talk is included in these lists:- All CMS events
