摘要
本文研究了一类特殊的左富足半群,即左GC-lpp-半群上的R^(*)-同余.我们利用类似正则半群上同余的核迹方法分别刻画了这类半群上具有相同核和迹的最大和最小同余.同时,我们也得到了左GC-lpp-半群上的幂等元R*-同余的一些性质,并建立了这种同余的结构.
In this paper,we consider the R^(*)-congruences on a class of special left abundant semigroups,namely,left GC-lpp semigroups.Applying the kernel and trace approach to the congruences on regular semigroups,we characterize the minimum and the maximum congruence with the same kernel and trace on left GC-lpp semigroups,respectively.Also,we obtain some characterizations and certain construction concerning the idempotent-separating R^(*)-congruences on left GC-lpp semigroups.
