Adjoint and duality for rank-metric codes in a skew polynomial framework

José Gómez-Torrecillas, F. J. Lobillo, Gabriel Navarro +1

Skew polynomial rings provide a fundamental example of noncommutative principal ideal domains. Special quotients of these rings yield matrix algebras that play a central role in th…

Character Values of $p$ -solvable groups on picky elements

Alexander Moretó, Gabriel Navarro, Noelia Rizo

A new conjecture on characters of finite groups, related to the McKay conjecture, was proposed recently by the first and third authors. In this paper, we prove it for $p$ -solvable…

Sum of the squares of the $p^{'}$ -character degrees

Nguyen N. Hung, J. Miquel Martínez, Gabriel Navarro

We study the sum of the squares of the irreducible character degrees not divisible by some prime $p$ , and its relationship with the the corresponding quantity in a $p$ -Sylow normal…
