On Hartwig–Nambooripad orders

Research output: Contribution to journal › Article › peer-review

Abstract

We obtain several equivalent characterizations for the Hartwig–Nambooripad order based on outer inverses. We also introduce new partial orders on arbitrary semigroups extending these regular semigroup orders. On epigroups these new partial orders admit characterizations in terms of outer inverses.
