TL-subgroups having the property (*)
We introduce the notion of a TL-subgroup having the property (*) that is a generalization of the notion of a generalized characteristic TL-subgroup as Abou-Zaid's notion was generalized in Kim (1994 [5]) and investigate interrelationship between the notion of a TL-subgroup having the property (*) and the notion of a generalized characteristic TL-subgroup.
