Frattini embeddings of normal subgroups [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
If N is a normal subgroup of the finite group G, there is a split extension X of an elementary abelian group by G such that N ⊴ X N \trianglelefteq X and N ∩ Φ ( G ) = Φ ( X ) N \cap \Phi (G) = \Phi (X) .

Groups with Few Normalizer Subgroups

open access: yesIrish Mathematical Society Bulletin, 2005
The behaviour of normalizer subgroups of a group has often a strong influence on the structure of the group it- self. In this paper groups with finitely many normalizers of subgroups with a given propertyare investigated, for vari- ous relevant choices of the property ´.

Weyl-Type Symmetry and Subalgebra Rigidity in von Neumann Algebras

open access: yesMathematics
We propose and develop a unified framework for Weyl-type symmetry in von Neumann algebras. Motivated by recent automorphism-rigidity phenomena that identify finite Weyl groups inside automorphism groups of crossed products arising from lattice actions on
