Controlling composition factors of a finite group by its character degree ratio [PDF]

open access: yes, 2013
For a finite nonabelian group $G$ let $\rat(G)$ be the largest ratio of degrees of two nonlinear irreducible characters of $G$. We show that nonabelian composition factors of $G$ are controlled by $\rat(G)$ in some sense.
