Partial GVZ-groups

Shawn T. Burkett, Mark L. Lewis

Following the literature, a group is called a group of central type if has an irreducible character that vanishes on . Motivated by this definition, we say…

A characterization of GVZ groups in terms of fully ramified characters

Shawn T. Burkett, Mark L. Lewis

In this paper, we obtain a characterization of GVZ-groups in terms of commutators and monolithic quotients. This characterization is based on counting formulas due to Gallagher.

Toward a Classification of the Supercharacter Theories of

Shawn T. Burkett, Mark L. Lewis

In this paper, we study the superscharacter theories of elementary abelian -groups of order . We show that the supercharacter theories that arise from the direct product co…

A Frobenius group analog for Camina triples

Shawn T. Burkett, Mark L. Lewis

Frobenius groups are an object of fundamental importance in finite group theory. As such, several generalizations of these groups have been considered. Some examples include: A Fro…

A characterization of Nested Groups in terms of conjugacy classes

Shawn T. Burkett, Mark L. Lewis

A group is nested if the centers of the irreducible characters form a chain. In this paper, we will show that there is a set of subgroups associated with the conjugacy classes of g…

GVZ-groups, Flat Groups, and CM-Groups

Shawn T. Burkett, Mark L. Lewis

We show that a group is a GVZ-group if and only if it is a flat group. We show that the nilpotence class of a GVZ-group is bounded by the number of distinct degrees of irreducible…

Characterizations of nested GVZ-groups by central series

Shawn T. Burkett, Mark L. Lewis

Many properties of groups can be defined by the existence of a particular normal series. The classic examples being solvability, supersolvability and nilpotence. Among the nilpoten…

A Jördan-Holder type theorem for supercharacter theories

Shawn T. Burkett

The Jordan-Hölder Theorem is a general term given to a collection of theorems about maximal chains in suitably nice lattices. For example, the well-known Jordan-Hölder type theorem…

An analog of nilpotence arising from supercharacter theory

Shawn T. Burkett

The goal of this paper is to generalize several group theoretic concepts such as the center and commutator subgroup, central series, and ultimately nilpotence to a supercharacter t…

Groups with exactly two supercharacter theories

Shawn Burkett, Jonathan Lamar, Mark L. Lewis +1

In this paper, we classify those finite groups with exactly two supercharacter theories. We show that the solvable groups with two supercharacter theories are and $S…
