Character degrees in $π$ -separable groups

N. Grittini

If a group $G$ is $π$ -separable, where $π$ is a set of primes, the set of irreducible characters $B_{π} (G) \cup B_{π^{'}} (G)$ can be defined. In this paper…

A note on cut groups of odd order

Nicola Grittini

A group $G$ is said to be cut if, for every $g \in G$ , each generator of $< g >$ is conjugated to either $g$ or $g^{- 1}$ . It is conjectured that a Sylow 3-subgroup $P$ of a c…

On zeros of irreducible characters lying in a normal subgroup

M. J. Felipe, N. Grittini, V. Sotomayor

Let $N$ be a normal subgroup of a finite group $G$ . In this paper, we consider the elements $g$ of $N$ such that $χ (g) \neq = 0$ for all irreducible characters $χ$ of $G$ . Such an ele…
