On some rational extension properties for and even-degree characters fixed by order-2 Galois automorphisms

A. A. Schaeffer Fry

In this note, we prove that if every character of a finite group fixed by an order-2 Galois automorphism has odd degree, then has a normal Sylow -subgroup. On the way, w…

The inductive McKay-Navarro conditions for the prime 2 and some groups of Lie type

L. Ruhstorfer, A. A. Schaeffer Fry

For a prime , the McKay conjecture suggests a bijection between the set of irreducible characters of a finite group with -degree and the corresponding set for the norm…

Galois-equivariant McKay bijections for primes dividing

A. A. Schaeffer Fry

We prove that for most groups of Lie type, the bijections used by Malle and Spaeth in the proof of Isaacs-Malle-Navarro's inductive McKay conditions for the prime 2 and odd primes…

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…

Fields of Character Values for Finite Special Unitary Groups

A. A. Schaeffer Fry, C. Ryan Vinroot

Turull has described the fields of values for characters of in terms of the parametrization of the characters of . In this article, we extend these results to th…

Galois Automorphisms on Harish-Chandra Series and Navarro's Self-Normalizing Sylow -Subgroup Conjecture

A. A. Schaeffer Fry

G. Navarro has conjectured a necessary and sufficient condition for a finite group to have a self-normalizing Sylow 2-subgroup, which is given in terms of the ordinary irreduci…

On Self-Normalising Sylow -Subgroups in Type A

Amanda Schaeffer Fry, Jay Taylor

Navarro has conjectured a necessary and sufficient condition for a finite group to have a self-normalising Sylow -subgroup, which is given in terms of the ordinary irreducib…
