摘　　要：本文研究了含幺可换环上对角子群在上三角子群中的扩群.利用构造一些集合,获得了此扩群的形式.In this paper, we make a study consisting of all upper triangular matrices over on the overgroups of the diagonal subgroup in the group arbitrary commutative rings with identity. By constructing some proper sets and computing, we obtain the form of these overgroups

关 键 词：对角子群 扩群 可换环
