Simple Groups Whose Prime Graph or Solvable Graph is Split

Mark L. Lewis, J. Mirzajani, A. R. Moghaddamfar +2

A graph is split if there is a partition of its vertex set into a clique and an independent set. The present paper is devoted to the splitness of some graphs related to finite simp…

The Complexity of Power Graphs Associated With Finite Groups

S. Kirkland, A. R. Moghaddamfar, S. Navid Salehy +2

The power graph of a finite group is the graph whose vertex set is , and two elements in are adjacent if one of them is a power of the other. The purpos…

Constructing solvable groups with derived length four and four character degrees

Mark L. Lewis

In this paper, we present a new method to construct solvable groups with derived length four and four character degrees. We then use this method to present a number of new families…
