摘 要: | 令Cpn是阶为pn的循环p群,F是特征为p的有限域。对于任何整数1≤l≤n,得到NmK2(FCpn])中无限多个非平凡的pl阶元素。事实上,这些元素组成NmK2(FCpn])的一个生成元集,并且NmK2(FCpn])的指数为pn。

Abstract: | Let Cpn be the cyclic p-group of order pn and F a finite field of characteristic p. For any integer 1 ≤ l ≤ n, we obtain infinitely many non-trivial elements of order pl in NmK2(FCpn]). In fact, these elements form a generating set of NmK2(FCpn]) and the exponent of NmK2(FCpn]) is pn. |
