Abstract

In recent years, a number of classical results connecting rational languages with finite semigroups have been extended to infinite-word languages using the notion of an ω-semigroup: a semigroup augmented with an associative infinite product. This paper takes a closer look at the associative infinite product itself. It suggests some improvements and presents a couple of new facts.
