On some rational extension properties for $G L_{n} (q)$ 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 $G$ fixed by an order-2 Galois automorphism has odd degree, then $G$ has a normal Sylow $2$ -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 $ℓ$ , the McKay conjecture suggests a bijection between the set of irreducible characters of a finite group with $ℓ^{'}$ -degree and the corresponding set for the norm…

Galois Automorphisms on Harish-Chandra Series and Navarro's Self-Normalizing Sylow $2$ -Subgroup Conjecture

A. A. Schaeffer Fry

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