Constructing solvable groups whose character degree graphs generalize the bowtie
Jacob Laubacher, Mark L. Lewis, Lorenzo Ravaglia +1
We present here a generalized construction of a finite solvable group whose prime character degree graph has the shape and structure of the bowtie graph. As with the original bowti…

Classifying Prime Character Degree Graphs With Eight Vertices
Mark L. Lewis, Andrew Summers
In this paper, an effort is made to classify which prime character degree graphs having eight vertices occur for some finite solvable group. To approach this, we compile known resu…

On the Number of Disconnected Character Degree Graphs Satisfying Pálfy's Inequality
Mark L. Lewis, Andrew Summers
Let be a finite solvable group with disconnected character degree graph . Under these conditions, it follows from a result of Pálfy that consists of two connect…
