Geir Ellingsrud, UiO, gives the Seminar in Algebra and Algebraic Geometry:
Abelian varieties XV: Abelian varieties are quotients of Jacobian varieties
Christian Voigt (Glasgow) will give a talk with title: The structure of quantum permutation groups
Abstract: Quantum permutation groups, introduced by Wang, are a quantum analogue of permutation groups. These quantum groups have a surprisingly rich structure, and they appear naturally in a variety of contexts, including combinatorics, operator algebras, and free probability. In this talk I will give an introduction to these quantum groups, and review some results on their structure. I will then present a computation of the K-groups of the C*-algebras associated with quantum permutation groups, relying on methods from the Baum-Connes conjecture.
