Abstract:
Given a nonempty set $\omega$ of primes and a nonempty formation $\mathfrak F$ of finite groups, we define the $\mathfrak F^\omega$-normalizer in a finite group and study their properties (existence, invariance under certain homomorphisms, conjugacy, embedding, and so on) in the case that $\mathfrak F$ is an $\omega$-local formation. We so develop the results of Carter, Hawkes, and Shemetkov on the $\mathfrak F$-normalizers in groups.
