### The R_\infty property for abelian groups

DOI: http://dx.doi.org/10.12775/TMNA.2015.066

#### Abstract

do not have the $R_\infty$ property, but this does not hold for all of them! In fact we construct an uncountable number of infinite countable abelian groups

which do have the $R_{\infty}$ property.

We also construct an abelian group such that the cardinality of the Reidemeister classes is uncountable for any automorphism of that group.
