Totaro's Question on Zero-Cycles on Torsors

Algebraic Geometry 2018-02-21 v1

Abstract

Let GG be a smooth connected linear algebraic group and XX be a GG-torsor. Totaro asked: if XX admits a zero-cycle of degree d1d \geq 1, then does XX have a closed \'etale point of degree dividing dd? While the literature contains affirmative answers in some special cases, we give an example to show that the answer is negative in general.
