Generalized ideals in ordered left almost semigroups

In this paper, we introduce the concept of (mn)-ideals in a non-associative ordered structure called an ordered \(\mathcal {LA}\)-semigroup. We also study the (mn)-regular class of an ordered \(\mathcal {LA}\)-semigroup in terms of (mn)-ideals.


Ordered \(\mathcal {LA}\)-semigroups Left invertive law Left identity and (m, n)-ideals
