Ternary semigroups

Semigroup Forum, 2010
A regularity condition on a ternary semigroup is introduced and some properties of regular ternary semigroups are investigated. A semigroup called cover of a ternary semigroup is constructed and some of its properties are studied.

*-orderable semigroups

Semigroup Forum, 2009
A semigroup algebra \(kS\) admits a total ordering if and only if the field \(k\) is formally real and \(S\) is a cancellative orderable semigroup. The case of \(*\)-orderability of \(kS\) is much harder. The notion of a \(*\)-ordering has been extended from division rings to general noncommutative rings in a series of papers by \textit{M.

On ordered $��$-semigroups ($��$-semigroups)

2014
We add here some further characterizations to the characterizations of strongly regular ordered $ $-semigroups already considered in Hacettepe J. Math. 42 (2013), 559--567. Our results generalize the characterizations of strongly regular ordered semigroups given in the Theorem in Math. Japon.
