Sanghoon Baek, Relationship between the Chow and Grothendieck Rings for Generic Flag Varieties
B266 IBS, Korea, Republic of
Algebraic Geometry Seminar
Speaker Sanghoon Baek KAIST Consider the canonical morphism from the Chow ring of a smooth variety X to the associated graded ring of the coniveau filtration on the Grothendieck ring of X. In general, this morphism is not injective. However, Nikita Karpenko conjectured that these two rings are isomorphic for a generic flag …
