线性近似群

Linear Approximate Groups

Emmanuel Breuillard, Ben Green, Terence Tao

摘要:

这是一个非正式的结果公告,将在一篇论文中详细描述和证明。我们给出了线性群如$\SL_n(k)$中近似子群的结构的各种结果。例如,推广的结果Helfgott(谁处理的情况下$n = 2$和3),我们表明,任何近似子群的$\SL_n(\F_q)$产生的组必须要么非常小,否则几乎所有的$\SL_n(\F_q)$。该参数对所有Chevalley组$G(\F_q)$都有效。

英文摘要:

This is an informal announcement of results to be described and proved in detail in a paper to appear. We give various results on the structure of approximate subgroups in linear groups such as $\SL_n(k)$. For example, generalising a result of Helfgott (who handled the cases $n = 2$ and 3), we show that any approximate subgroup of $\SL_n(\F_q)$ which generates the group must be either very small or else nearly all of $\SL_n(\F_q)$. The argument is valid for all Chevalley groups $G(\F_q)$.
