the universal $mathcal{air}$- compactification of a semigroup
the universal $mathcal{air}$- compactification of a semigroup
Abstract
in this paper we establish a characterization of abelian compact hausdorff semigroups with unique idempotent and ideal retraction property. we also introduce a function algebra on a semitopological semigroup whose associated semigroup compactification is universal withrespect to these properties.
