摘要
刻画P-正则半群上的特征迹关系κ.给出任一强P-同余所在κ-类中最大元的结构,并证明每个κ-类均为强P-同余格Λp(S)的完备子格,最后给出任意2个强P-同余具有κ-关系的几种等价条件.
The characteristic kernel relation κof a P-regular semigroup S （P） is described. For a given strong P-congruence rho it is given that the structures of the greatest element of the κ-class of rho. Moreover it is proved that each κ-class of a strong P-congruence is a complete sublattice of the class of Ap （S）. Finally several equivalent conditions are given for two strong P-congruences to have a κ-relation.
