借助(*,～)-格林关系刻画r-宽大半群S上的几类好同余.给出r-宽大半群S上几类好同余,如最小(左;右)正则带类-好同余,最小(左;右)正则拟弱适当半群类-好同余等的刻画.
Several classes of good congruences on r-wide semigroups
Several classes of good congruences on r-wide semigroups are characterized by(*,～)-Green's relations.It is showed that for r-wide semigroups,such as the least class of(left;right)regular bands-good congruence,the least class of(left;right)regular quasi-weakly adequate semigroups-good congruence and so on.
