On the Wielandt subgroup of generalized FC-groups
International Journal of Algebra and Computation, 2014 We extend to soluble FC*-groups, the class of generalized FC-groups introduced in [de Giovanni, Russo and Vincenzi, Groups with restricted conjugacy classes, Serdica Math. J. 28(3) (2002) 241–254], the characterization of finite soluble T-groups, and some results on the Wielandt subgroup, obtained recently in [Kaplan, On finite T-groups and the ...

, 2011 It is well-known that groups with finite conjugacy classes (i.e., FC-groups) can be considered as the most natural tool in order to study properties which are common both to finite groups and abelian groups. The attempt to investigate wider classes of groups generalizing both finiteness and nilpotency suggests the introduction of the classes of FCn ...

Conjugately dense subgroups in generalized FC-groups.
2009Summary: A subgroup \(H\) of a group \(G\) is called conjugately dense in \(G\) if \(H\) has nonempty intersection with each class of conjugate elements in \(G\). The knowledge of conjugately dense subgroups is related with an unsolved problem in group theory, as testified in the Kourovka Notebook.
