Torelli群的小发电机组

Small generating sets for the Torelli group

Andrew Putman

摘要:

证明了Dennis Johnson的一个猜想,证明了映射类群的Torelli子群有一个有限生成集,其大小随曲面的亏格成立方增长.我们的主要工具是一个新的空间称为处理图上的Torelli群行为cocompanies。

英文摘要:

Proving a conjecture of Dennis Johnson, we show that the Torelli subgroup of the mapping class group has a finite generating set whose size grows cubically with respect to the genus of the surface. Our main tool is a new space called the handle graph on which the Torelli group acts cocompactly.
