摘要
所有双理想都是理想的半群定义为I0-半群,所有子半群都是双理想的半群定义为C0-半群;得到正则半群S是I0-半群当且仅当B(S)是半格;π-正则半群S是C0-半群,则S是矩形带的幂零扩张.
Abstract
The semigroup whose bi-ideals are ideals is called I0-semigroup,the semigroup whose subsemigroups are bi-ideals is called C0-semigroup;the following results are given: the sufficient and necessary condition of regular seimgroup S being I0-semigroup is B(S) being semilattice;if the π-regular seimgroupS is C0-semigroup,Sis a nil-extension of rectangular band.
