富足半群的拟理想恰当断面

摘要

The properties of abundant semigroups with quasi-ideal adequate transversals were discussed in this paper.Their decomposition form of the product of two elements and I and Λ,equivalent characterisation of the left and right normal bands of the abundant semigroup S with the quasi-ideal adequate transversal S0,were given.%给出了具有拟理想恰当断面的富足半群中两个元素乘积的分解式,给出了含有拟理想恰当断面S0的富足半群S中I和Λ分别作成S的左正规带及右正规带的等价刻画,并对含有拟理想恰当断面的富足半群的性质进行了讨论.
