关于Torsors上零圈的Totaro问题

Totaro's Question on Zero-Cycles on Torsors

Reed Gordon-Sarney, Venapally Suresh

摘要:

设$G$是光滑连通线性代数群,$X$是$G$ -扭子.户太郎问:如果$X$允许一个度为$d \geq 1$的零圈,那么$X$是否有一个度为$d$的闭合顶点?虽然文献中包含肯定的答案在某些特殊情况下,我们给出一个例子来表明,答案是否定的。

英文摘要:

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