3-流形群的稳定表示长度

Stable presentation length of 3-manifold groups

Ken'ichi Yoshida

摘要:

我们引入了一个双呈现群的稳定呈现长度。三维流形的基本群的稳定表示长度可以看作是单纯体积的一个类比。我们证明了稳定表示长度与单纯体积一样具有加法性质,并且闭3-流形的单纯体积由其基本群的稳定表示长度的常数倍上下有界.

英文摘要:

We introduce the stable presentation length of a finitely presented group. The stable presentation length of the fundamental group of a 3-manifold can be considered as an analogue of the simplicial volume. We show that the stable presentation length have some additive properties like the simplicial volume, and the simplicial volume of a closed 3-manifold is bounded from above and below by constant multiples of the stable presentation length of its fundamental group.
