摘要
根据A-上环(A是代数)的类群元的定义及有关性质,本文给出T-余单子(T是单子)的类群元的定义,研究此类群元的存在条件,并给出类群元与缠绕结构之间的相关性质.
According to the definition and some properties of the group - like element of A - eorings （ A is an algebra）, firstly the definition of the group - like element of T - comonad is introduced, then the existence of group - like element is stud- ied,and lastly some properties between group like element and entwining structure of monad and comonad are given.
