New results on finite T-groups

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.
