摘要 设G是有限群,并设χ是G的一个(复)特征标.如果χ的值是有理数,则称χ是有理值的.如果G的每个不可约特征标都是有理值的,则称G是有理群.主要目的是对若干有理群进行分类.此外,给出一个应用例子,并对关于有理群的一个已知结果给出纯群论的内在刻划. A finite group G is called a rational group, if every character of G is rationally-valued. In this paper, we classify some rational groups. In addition, we give an example of application, and a group-theory proof for a known result about rational groups.
