Introduction The purpose of this paper is to formulate recognition criteria for the ,normalizer, and the p-,normalizer, of a maximal torus of a p-compact group.

Covering by subgroups, ,Normalizer,, Finite p-group. 1. 2 AMIRI,HAJIANDJAFARIANAMIRI A ,centralizer, covering of a group G is a covering Γ of G such that all members of Γ are the centralizers of some elements in G i.e. Γ = {CG(x1),··· ,CG(xn)} for some non-central elements xis in G and pos-

n) the ,centralizer, C W (w) of an element w 2W is in a similar way a semidirect product of the ,centralizer, of w in a suitable small parabolic subgroup W J with complement isomorphic to the ,normalizer, complement N J. Then we use this result to give a new short proof of Solomon’s Character Formula and discuss its connection to MacMahon master ...

Talk:Centralizer and normalizer - Wikipedia

In the beginning, it says The ,centralizer, and ,normalizer, of S are subgroups of G, and can provide insight into the structure of G. Can this be made more specific? In which way do they provide insight into the structure of G? Is there a particular ,theorem, indicating this? Zaunlen 15:14, 10 November 2019 (UTC)

Groups with Few Normalizer Subgroups

as x normalizes A, the ,normalizer, NG(A) must have ﬁnite index in G. Thus all abelian subgroups of CG(x) are almost normal, and so CG(x) is central-by-ﬁnite (see [10]). On the other hand, the index jG: CG(x)j is ﬁnite, so that G is an abelian-by-ﬁnite FC-group and hence G=Z(G) is ﬁnite. ⁄ Polovicki˘ı’s ,theorem, …
