Speaker: Alexander Neshitov (Western)
Title: "Torsion in codimension 2 Chow groups of classifying spaces of algebraic tori"
Room: Zoom: 998 5635 1219

Abstract: Chow groups of classifying spaces of tori arise in the theory of cohomological invariants. In this talk we will give an overview of a computer-assisted proof that CH2 groups of the classifying space BT are torsion free when dim(T)<=5
