广义Dehn函数II

Generalized Dehn Functions II

Chad Groft

摘要:

我们建立的存在性,有限性和唯一性的缩放各种等周配置文件的一组,在所有的维度。我们还证明了这些轮廓在4维和更高维上都是一致的;特别是,当n至少为3时,第n个Dehn函数等于FV^{n+1}。即使对于维度3,也存在显著重叠。当一个群体有可判定的字问题时,这对其个人资料的增长率有轻微的影响。我们还建立了高连通黎曼流形的度量类比。

英文摘要:

We establish the existence, finiteness, and uniqueness up to scaling of various isoperimetric profiles of a group, in all dimensions. We also show that these profiles all coincide in dimensions 4 and higher; in particular, the nth Dehn function is equal to FV^{n+1} for n at least 3. Even for dimension 3, there is significant overlap. When a group has decidable word problem, this has mild consequences for the growth rates of its profiles. We also establish a metric analogue for highly connected Riemannian manifolds.
