摘要:

本文研究了 virtually abelian 群上与扭曲共轭相关的几个增长函数的渐近性。首先,研究了扭曲共轭增长函数,该函数计算与单位元周围半径为 r 的球相交的扭曲共轭类数量。随后,研究了衡量给定扭曲共轭类与单位元周围的球的交集大小的函数。最后,研究了给定 virtually abelian 群的某些有限商中诱导的扭曲共轭类数量。在每种情况下,我们都得到了这些增长函数的多项式渐近行为。

英文摘要:

In this paper, we study the asymptotics of several growth functions related to twisted conjugacy on virtually abelian groups. First, we study the twisted conjugacy growth function, which counts the number of twisted conjugacy classes intersecting the ball of radius r around the identity element. Thereafter we study the function that measures the size of the intersection of a given twisted conjugacy class with the balls around the identity element. Finally, we study the number of induced twisted conjugacy classes in certain finite quotients of the given virtually abelian group. In each of these cases we obtain a polynomial asymptotic behaviour of these growth functions.
