Degrees of -rational characters and normality of Sylow -subgroups
Silvio Dolfi, Pham Huu Tiep, Yu Zeng
Several refinements of (the normality part of) the celebrated Itô--Michler theorem were obtained during the last two decades, in which the condition of having -degree, for a fi…
Finite groups whose real irreducible representations have unique dimensions
Thomas Breuer, Frank Calegari, Silvio Dolfi +2
We determine the finite groups whose real irreducible representations have different degrees.
On the structure of the character degree graphs having diameter three
Silvio Dolfi, Roghayeh Hafezieh, Pablo Spiga
The structure of the character degree graphs , i.e. the prime graphs on the set of the irreducible character degrees of a finite group , such that is…
Finite groups with a small proportion of vanishing elements
Dongfang Yang, Yu Zeng, Silvio Dolfi
The function , measuring the proportion of the elements of a finite group that are zeros of irreducible characters of , takes (as proved in [12])…
Non-solvable groups whose character degree graph has a cut-vertex. III
S. Dolfi, E. Pacifici, L. Sanus
Let be a finite group. Denoting by the set of the degrees of the irreducible complex characters of , we consider the {\it character degree graph} of : this…
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…
