In this paper we investigate the class of all completely 0-simple semigroups of left quotients of a given semigroup S. We show that (if the class is non-empty) it has a ‘greatest’ member ∈S which is in a sense the free completely 0-simple semigroup on S, and describe how the other members can be obtained as homomorphic images of [Formula: see text].
