SUMMARY:Workshop / Seminar:Chow Vanishing and Motives of Cluster Varieties
DESCRIPTION:Progress over the last decade has shown that the cohomologies of full rank\, locally acyclic cluster varieties enjoy remarkable combinatorial structures. Crucial in this program has been the observation that these cohomology groups are\, in certain Hodge theoretic senses\, about as simple as possible. In this talk we will discuss a motivic lift of this observation. In particular we establish that the Voevodsky motives of really full rank sink-recurrent cluster varieties are mixed Tate and split over Q (strengthening results of Lam and Speyer)\, and we prove that their integral Chow groups are all trivial.

SUMMARY:Workshop / Seminar:Algebraic cobordism rings of wonderful varieties and matroids
DESCRIPTION:An exceptional\, integral isomorphism was found between the K-ring and Chow ring of the wonderful variety of a hyperplane arrangement in works of Berget--Eur--Spink--Tseng and Larson--Li--Payne--Proudfoot. I will discuss my work with Ethan Partida\, where we examine this exceptional isomorphism from the point of view of formal group laws\, and extend it to an exceptional isomorphism between the algebraic cobordism ring and (extended) Chow ring of the wonderful variety.
