Equidivisible pseudovarieties of semigroups
 
 
Description:  A semigroup is said to be equidivisible if distinct factorizations of an element have always a common refinement. Groups and free semigroups are examples of equidivisible semigroups.

We give a complete characterization of pseudovarieties of semigroups whose finitely generated relatively free profinite semigroups are equidivisible.

This is joint work with Jorge Almeida.
