Non-solvable groups whose character degree graph has a cut-vertex. II

Silvio Dolfi, Emanuele Pacifici, Lucia Sanus

Let $G$ be a finite group, and let $cd (G)$ denote the set of degrees of the irreducible complex characters of $G$ . Define then the character degree graph $Δ (G)$ as the (simp…

Non-solvable groups whose character degree graph has a cut-vertex. I

Silvio Dolfi, Emanuele Pacifici, Lucia Sanus +1

Let G be a finite group. Denoting by cd(G) the set of degrees of the irreducible complex characters of G, we consider the character degree graph of G: this is the (simple undirecte…

On the proportion of vanishing elements in finite groups

Yu Zeng, Dongfang Yang, Silvio Dolfi

We prove that the function $P_{v} (G)$ , measuring the proportion of the elements of a finite group $G$ that are zeros of irreducible characters of $G$ , takes very…
