On the conjugacy separability in the class of finite $p$-groups of finitely generated nilpotent groups

Abstract

It is proved that for any prime $p$ a finitely generated nilpotent group is conjugacy separable in the class of finite $p$-groups if and only if the torsion subgroup of it is a finite $p$-group and the quotient group by the torsion subgroup is abelian.
