A classification of prime graphs of pseudo-solvable groups

Ziyu Huang, Thomas Michael Keller, Shane Kissinger +3

The prime graph $\Gamma (G)$ of a finite group $G$ (also known as the Gruenberg-Kegel graph) has as its vertices the prime divisors of $|G|$, and $p\text{-}q$ is an edge in $\Gamma (G)$ if and o…
