| Abstract: | We introduce the concept of a quasi-C-Ehresmann semigroup. Some
special quasi-C-Ehresmann semigroups will be considered. We will
show that the quasi-C-Ehresmann semigroups are special
U-semiabundant semigroups and orthodox U-liberal semigroups,
which have been recently studied by several authors. Some
characterization theorems of this new class of semigroups are
obtained. Many results of quasi-C-semigroups in the literature
can be extended to quasi-C-Ehresmann Semigroups. |
