本文将K2(F[G×Zp])表示为K2(FG)与初等交换p-群的直和,并利用它计算了当F是奇素特征的有限域,G是p ~ 2-秩≤1的有限交换群时的K2(FG).我们还计算了HDR 1(FG),如果F是一个有限域的奇特征p和G是一个有限阿贝尔p-群。
In this paper, we represent K2(F[G×Zp]) as the direct sum of K2(FG) and an elementary abelian p-group; using this we calculate K2(FG) when F is a finite field of odd prime characteristic and G is a finite abelian group of p2-rank ≤1. We also compute HDR1(FG) if F is a finite field of odd characteristic p and G is a finite abelian p-group.
