Galois action on the principal block and cyclic Sylow subgroups

Noelia Rizo, A. A. Schaeffer Fry, Carolina Vallejo

We characterize finite groups having a cyclic Sylow p-subgroup in terms of the action of a specific Galois automorphism on the principal p-block for p=2,3. We show that the analog…

A reduction theorem for the Galois-McKay conjecture

Gabriel Navarro, Britta Späth, Carolina Vallejo

We generalize the theory of ordering character triples, developed by Navarro and Späth, by taking into account the action of Galois automorphisms on characters. This new technique,…

Characters of $π^{'}$ -degree

Eugenio Giannelli, Mandi Schaeffer Fry, Carolina Vallejo

Let $G$ be a finite group and let $π$ be a set of primes. Write $Irr_{π^{'}} (G)$ for the set of irreducible characters of degree not divisible by any prime in $π$ . We show th…
