群的拟等距嵌入定理

A quasi-isometric embedding theorem for groups

A. Olshanskii, D. Osin

摘要:

我们证明了每个群$H$关于某个左不变度量最多指数增长性,允许一个双Lipschitz嵌入到一个有限生成群$G$中,使得$G$是顺从的(分别是,可解的,满足一个非平凡的恒等式,初等顺从的,有限分解复杂性的,等等).每当$H$。我们还讨论了Lipschitz嵌入到一致凸巴拿赫空间的压缩函数,Følner函数和顺从群的初等类的一些应用。

英文摘要:

We show that every group $H$ of at most exponential growth with respect to some left invariant metric admits a bi-Lipschitz embedding into a finitely generated group $G$ such that $G$ is amenable (respectively, solvable, satisfies a non-trivial identity, elementary amenable, of finite decomposition complexity, etc.) whenever $H$ is. We also discuss some applications to compression functions of Lipschitz embeddings into uniformly convex Banach spaces, Følner functions, and elementary classes of amenable groups.
