类人猿、幂零群和Gowers范数

Parallelepipeds, Nilpotent Groups, and Gowers Norms

Bernard Host, Bryna Kra

摘要:

在Szemeredi定理的证明中,Gowers引入了定义在平行六面体结构上的某些规范。一个自然的问题是在哪些集合上可以定义一个平行六面体结构(以及一个Gowers范数)。我们专注于2和3维,并显示当这可能的,并描述了平行六面体结构幂零群之间的对应关系。

英文摘要:

In his proof of Szemeredi's Theorem, Gowers introduced certain norms that are defined on a parallelepiped structure. A natural question is on which sets a parallelepiped structure (and thus a Gowers norm) can be defined. We focus on dimensions 2 and 3 and show when this possible, and describe a correspondence between the parallelepiped structures nilpotent groups.
