On the cut-set of the Gruenberg-Kegel graph of a finite solvable group

Lorenzo Bonazzi

Let $Γ (G)$ be the Gruenberg-Kegel graph of a finite group $G$ . We prove that if $G$ is solvable and $σ$ is a cut-set for $Γ (G)$ , then $G$ has a $σ$ -series of length $5$ whose facto…

Finite groups whose real classes have prime-power size

Lorenzo Bonazzi

We present a characterization of the finite groups in which all real classes have prime powers size.

Finite non-solvable groups whose real degrees are prime-powers

Lorenzo Bonazzi

We present a description of non-solvable groups in which all real irreducible character degrees are prime-power numbers.
