摘要
在这篇注记中,通过研究两个有限群直积的整群环的正规化挠单位的偏增广,证明了在某些条件下这些正规化挠单位与该群中的元素在有理群代数中共轭.
In this note, we investigate the partial augmentations of the normalized torsion units in integral group rings of the direct product of two finite groups. It is proved that every normalized torsion unit is conjugate to one element in the group within the rational group algebra under some conditions.
