On identities in groups of fractions of cancellative semigroups

S. V. Ivanov, A. M. Storozhev

To solve two problems of Bergman stated in 1981, we construct a group $G$ such that $G$ contains a free noncyclic subgroup (hence, $G$ satisfies no group identity) and $G$ , as a gr…

Non-hopfian relatively free groups

S. V. Ivanov, A. M. Storozhev

To solve problems of Gilbert Baumslag and Hanna Neumann, posed in the 1960's, we construct a nontrivial variety of groups all of whose noncyclic free groups are non-hopfian.
