正则p-群的余指数

The Coexponent of a Regular p-Group

Paul J. Sanders

摘要:

对于正则p-群的幂零类,导出了一个关于其余指数的精确界,并用来证明当p和n足够大时,具有给定的固定余指数的p^n阶群的个数与n无关。在余指数为3的情况下,计算了显式公式。

英文摘要:

A sharp bound is derived for the nilpotency class of a regular p-group in terms of its coexponent, and is used to show that the number of groups of order p^n with a given fixed coexponent, is independent of n, for p and n sufficiently large. Explicit formulae are calculated in the case of coexponent 3.
