DESCRIPTION:Speakers: Xi Chen (Alberta/Bonn)\n\nFor a smooth surface of de
 gree at least 4 in ${\\mathbbP}^3$\, Mumford proved that its Chow group of
  0-cycles are nontrivial.As the degree increases\, we are expecting the gr
 oup to become largerin some sense. Voisin proved that no two distinct poin
 ts arerationally equivalent on a very general surface of degree at least 7
 .We improved her result to degree 6\, which is optimal. This is a jointwor
 k with James D. Lewis and Mao Sheng.\n\nhttps://math-events.uni-bonn.de/ev
