On identities in groups of fractions of cancellative semigroups

Group Theory 2007-05-23 v1

Abstract

To solve two problems of Bergman stated in 1981, we construct a group GG such that GG contains a free noncyclic subgroup (hence, GG satisfies no group identity) and GG, as a group, is generated by its subsemigroup that satisfies a nontrivial semigroup identity.
