Finite groups and the class-size prime graph revisited
Víctor Sotomayor
We report on recent progress concerning the relationship that exists between the algebraic structure of a finite group and certain features of its class-size prime graph.
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 products of groups and indices not divisible by a given prime
María-José Felipe, Lev S. Kazarin, Ana Martínez-Pastor +1
Let the group be the product of subgroups and , and let be a prime. We prove that does not divide the conjugacy class size (index) of each -regular eleme…
On zeros of irreducible characters lying in a normal subgroup
M. J. Felipe, N. Grittini, V. Sotomayor
Let be a normal subgroup of a finite group . In this paper, we consider the elements of such that for all irreducible characters of . Such an ele…
