Kernels of $$p'$$-Degree Irreducible Characters

Methods and questions in character degrees of finite groups

“…We conclude this section with a proof of Corollary B of [53] using the ideas in this section instead of Theorem A of [53].…”

“…On the other hand, in joint work with N. Rizo [53], we have obtained an extension of the classical theorem of Broline-Garrison on character kernels (Theorem 12.19 of [27]) to irreducible characters of p ′ -degree, where p is a prime.…”
