A group-theoretical interpretation of the word problem for free idempotent generated semigroups [PDF]
Advances in Mathematics, 2019 The set of idempotents of any semigroup carries the structure of a biordered set, which contains a great deal of information concerning the idempotent generated subsemigroup of the semigroup in question. This leads to the construction of a free idempotent generated semigroup $\mathsf{IG}(\mathcal{E})$ - the `free-est' semigroup with a given biordered ...

A class of bisimple, idempotent-generated congruence-free semigroups
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1981SynopsisLet X be a set with infinite regular cardinality m. Within the full transformation semigroup ℑ(X) a subsemigroup Sm is described which is bisimple and idempotent-generated. Its minimum non-trivial homomorphic image has both these properties and is also congruence-free.
