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…
