本原素除子与$n$次分圆多项式

Primitive prime divisors and the $n$-th cyclotomic polynomial

S. P. Glasby, Frank Lübeck, Alice C. Niemeyer, Cheryl E. Praeger

摘要:

本原素除子在群论和数论中起着重要的作用。研究了一个数论量$Φ^*_n(q)$,它与分圆多项式$Φ_n(x)$和$q^n-1$的本原素除子密切相关.我们给出了$Φ^*_n(q)$的新定义,并证明了它与Hering给出的定义是等价的.给定正常数$c$和$k$,我们给出了一个确定所有$(n,q)$与$Φ^*_n(q)\le cn^k$对的算法.这个算法是用来推广(和纠正)的结果,这是有用的分类某些家庭的有限线性群的子群。

英文摘要:

Primitive prime divisors play an important role in group theory and number theory. We study a certain number theoretic quantity, called $Φ^*_n(q)$, which is closely related to the cyclotomic polynomial $Φ_n(x)$ and to primitive prime divisors of $q^n-1$. Our definition of $Φ^*_n(q)$ is novel, and we prove it is equivalent to the definition given by Hering. Given positive constants $c$ and $k$, we give an algorithm for determining all pairs $(n,q)$ with $Φ^*_n(q)\le cn^k$. This algorithm is used to extend (and correct) a result of Hering which is useful for classifying certain families of subgroups of finite linear groups.
