Subclasses of locally Minimax Groups Closed under Normal Joins

Journal of the London Mathematical Society, 1997
A famous theorem of Hirsch and Plotkin states that in any group \(G\) the subgroup generated by locally nilpotent normal subgroups is likewise locally nilpotent, so that in particular \(G\) has a largest locally nilpotent normal subgroup (the Hirsch-Plotkin radical of \(G\)).

On permutable subgroups of soluble minimax groups

Archiv der Mathematik, 1985
A subgroup H of a group is called permutable if \(HK=KH\) for every subgroup K. Also a subgroup of a group G is said to be core-free, if it contains no nontrivial normal subgroups of G. The following result is established. Theorem. A core-free permutable subgroup of a residually finite soluble minimax group is contained in the hypercentre.

On maximal subgroups of minimax groups

1995
It is known, that if \(G\) is a finitely generated soluble group such that \(G/\Phi(G)\) is nilpotent then \(G\) is nilpotent too, where \(\Phi(G)\) is the Frattini subgroup of the group \(G\). J. C. Lennox proved that if \(G\) is a finitely generated soluble group such that \(G/\Phi(G)\) is finite-by- nilpotent then \(G\) is finite-by-nilpotent.
