Rezumat

Here we extend the notion of -groups in semigroups without order to ordered semigroups. We call them  π -t-simple ordered semigroups. Our approach allows one to see the relations between Archimedean (t-Archimedean) ordered semigroups and  π -t-simple ordered semigroups. Furthermore we show that a completely  π -regular ordered semigroup S such that for any a; b € S there exists an ordered idempotent e € S with the property that ab; brar 2 p H(e) for any r € N, is a complete semilattice of π -t-simple ordered semigroups and conversely

Cuvinte-cheie
Archimedean, completely π-regular, nil-extension, ordered idempotent, π-t-simple ordered semigroup.
