关于$p$ -群的Schur乘子阶的界

Bounds On the order of the Schur multiplier of $p$-groups

Pradeep Kumar Rai

摘要:

1956年,Green给出了$p$ -群的Schur乘子的阶的一个界。这个界,作为群的阶的函数给出,是最好的可能。从那时起,通过向函数添加其他输入,例如群的生成元的最小数量和导出子群的阶,边界已经被细化了无数次。我们通过添加另一个输入(群的幂零性类)来加强这些界限。幂零类2和最大类的具体情况进行了更详细的讨论。

英文摘要:

In 1956, Green provided a bound on the order of the Schur multiplier of $p$-groups. This bound, given as a function of the order of the group, is the best possible. Since then, the bound has been refined numerous times by adding other inputs to the function, such as, the minimal number of generators of the group and the order of the derived subgroup. We strengthen these bounds by adding another input, the group's nilpotency class. The specific cases of nilpotency class 2 and maximal class are discussed in greater detail.
