最大步长的随机幂零群

Random Nilpotent Groups of Maximal Step

Phillip Harris

摘要:

设$G$是由$U_n(\mathbb{Z})$中长度为$\ell$的两个随机字生成的随机无挠幂零群.让$\ell$作为$n$的函数增长,我们分析了由$U_n(\mathbb{Z})$的步长限制的$G$的步长。本文证明了Delp,Dymarz和Schafer-Cohen的一个猜想,即全阶跃的门限函数是$\ell = n^2$ .

英文摘要:

Let $G$ be a random torsion-free nilpotent group generated by two random words of length $\ell$ in $U_n(\mathbb{Z})$. Letting $\ell$ grow as a function of $n$, we analyze the step of $G$, which is bounded by the step of $U_n(\mathbb{Z})$. We prove a conjecture of Delp, Dymarz, and Schafer-Cohen, that the threshold function for full step is $\ell = n^2$.
