Characterizing finite groups whose enhanced power graphs have universal vertices

David G. Costanzo, Mark L. Lewis, Stefano Schmidt +2

Let $G$ be a finite group and construct a graph $Δ (G)$ by taking $G ∖ {1}$ as the vertex set of $Δ (G)$ and by drawing an edge between two vertices $x$ and $y$ if $\langle x…

Finite solvable tidy Groups whose orders are divisible by two primes

Nicolas F. Beike, Rachel Carleton, David G. Costanzo +4

In this paper, we investigate finite solvable tidy groups. We classify the tidy ${p, q}$ -groups. Combining this with a previous result, we are able to characterize the finite t…
