The 0-minimal ideal of the global of a combinatorial completely 0-simple semigroup
The global of a combinatorial completely 0-simple semigroup S has been proved by the first of the authors to have a unique 0-minimal ideal C(S) [J. Algebra 98, 319-361 (1986; Zbl 0577.20053)]. This ideal determines S up to isomorphism.
