New results on finite T-groups
Abstract:
A group is called a T-group if all its subnormal subgroups are
normal. This concept was widely studied since the seminal paper by
Gaschuetz (1957). In this talk we present new characterizations of finite
solvable T-groups. Two characterizations are connected to maximal subgroups
and their properties. Another characterization is connected to products of
conjugate subgroups.
