Zeros of irreducible characters in factorised groups

M. J. Felipe, A. Martínez-Pastor, V. M. Ortiz-Sotomayor

An element $g$ of a finite group $G$ is said to be vanishing in $G$ if there exists an irreducible character $χ$ of $G$ such that $χ (g) = 0$ ; in this case, $g$ is also called a zero…

Prime power indices in factorised groups

M. J. Felipe, A. Martínez-Pastor, V. M. Ortiz-Sotomayor

Let the group $G = A B$ be the product of the subgroups $A$ and $B$ . We determine some structural properties of $G$ when the $p$ -elements in $A \cup B$ have prime power indices in $G…

Square-free class sizes in products of groups

M. J. Felipe, A. Martínez-Pastor, V. M. Ortiz-Sotomayor

We obtain some structural properties of a factorised group $G = A B$ , given that the conjugacy class sizes of certain elements in $A \cup B$ are not divisible by $p^{2}$ , for some prim…
