BQ-elements of some semigroups
View through CrossRef
A -element of a semigroup is an element such that the bi-ideal and the quasi-ideal of generated by coincide, i.e., . -elements are a generalization of regular elements in semigroups. In this research, the -elements of the semigroup are characterized. We also characterize the -elements of some semigroups of transformations of sets and linear transformations. In addition, the -elements of the following semigroups are determined : (Zn,) , (Zn,) , (Zn,) , the additive interval semigroups and the multiplicative interval semigroups on ℝ.
