# On groups whose subnormal abelian subgroups are normal

@inproceedings{Kurdachenko2021OnGW, title={On groups whose subnormal abelian subgroups are normal}, author={Leonid A. Kurdachenko and Javier Otal and Igor Ya. Subbotin}, year={2021} }

In the current paper we study the groups, whose subnormal abelian subgroups are normal. We obtained a quite detailed description of such hyperabelian groups with a periodic Baer radical. The description of hyperabelian Lie algebras, whose abelian subideals are ideals, is also obtained.

Abstract A subgroup H of a group G is said to be permutable in G, if HK = KH for every subgroup K of G. Every permutable subgroup is ascendant, but, in general, the converse is far from being true.…

A transitively normal subgroup of a group G is one that is normal in every subgroup in which it is subnormal. This concept is obviously related to the transitivity of normality because the latter…
