同伦幂零群幂群的环面定理

A Torus Theorem for homotopy nilpotent groups

Cristina Costoya, Jérôme Scherer, Antonio Viruel

摘要:

离散群的幂零性可以用中心扩张来定义。在本文中,类似的定义空间的主要纤维化有无限的闭路空间作为纤维,产生一个新的不变量,我们比较经典的余范畴,但也与最近的概念同伦幂零介绍了Biedermann和德怀尔。这使我们能够在Hubbuck环面定理的精神下刻画有限同伦幂闭路空间,以及$p$ -紧群和$p$ -诺特群的相应结果。

英文摘要:

Nilpotency for discrete groups can be defined in terms of central extensions. In this paper, the analogous definition for spaces is stated in terms of principal fibrations having infinite loop spaces as fibers, yielding a new invariant we compare with classical cocategory, but also with the more recent notion of homotopy nilpotency introduced by Biedermann and Dwyer. This allows us to characterize finite homotopy nilpotent loop spaces in the spirit of Hubbuck's Torus Theorem, and corresponding results for $p$-compact groups and $p$-Noetherian groups.
