| Abstract: | We introduce the concept of orthodox Ehresmann semigroups. We will show that the orthodox Ehresmann semigroups are special U-semiabundant semigroups, which have been recently studied by several authors. Some characterization theorems of this new class of semigroups are obtained. Some special orthodox Ehresmann semigroups are considered. |
