group member

In this paper,we investigate unit regularity by virtue of group members in regular rings.

利用环中的群元素刻画了环的单位正则性。

The paper also constructs the set of all grouplike elements of wU_q(■).

定义了一个具有弱Hopf代数结构的弱量子代数wU_q(■),构造了它的类群元素集,并给出了两个不同参数的弱量子代数同构的条件。

Let Cn be the symmetric inverse semigroup on the finite set Xn={1,2,…,n},and ξ,σ are two group elements of Cn.
