摘要
设P是正则半群S的全子集,正则半群上的任意同余和P-部分核正规系之间存在一一对应关系.给出了由P-部分核正规系决定的同余一个新的刻画且证明了正则半群上的同余和P-部分同余对(K,ξ)之间存在一一对应关系.
Let P be an arbitrary full subset of the regular semigroup S.A construction of the unique congruence associated with such a P-partial kernel normal system has obtained.A new characterization of congruences determined by P-partial kernel normal system on regular semigroups is given here and it shows that each congruence on a regular semigroup is uniquely determined by its certain P-partial congruencepair(K,ξ).
