Equivariant Chow motives of homogeneous varieties
Emmy-Noether-Seminar

Speaker: Prof. Dr. Nikita Semenov (LMU München)
Host: Knop
Room: 04.363

In the talk I will present a formula for the equivariant Chow motive of the variety of full flags of a split semisimple algebraic group. This formula involves degrees of generators of the kernel of the characteristic map, which were computed by Victor Kac. In some cases Kac's degrees coincide with codimensions of Rost motives, where they have non-zero Chow groups. Besides, they are related to Chow groups of classifying spaces of some algebraic groups. In the talk I will explain these relationships. This is a joint work with Victor Petrov.
