Peeter Puusemp (Tallinn): On endomorphisms and endomorphism monoids of groups and semigroups

Abstract: In the first part of the talk, results on endomorphisms and endomorphism monoids of groups will be presented. Main attention is turned to the question of the determinability of groups by their endomorpism semigroups in the class of all groups. In the second part of the talk, a short overview of results on endomorphism monoids of semigroups will be given.
