On \(A\)-radicals. (English) Zbl 1150.16018
A Kurosh-Amitsur radical \(\gamma\) of rings is said to be an \(A\)-radical if for any two rings \(A,B\) with isomorphic additive groups \(A\in\gamma\Rightarrow B\in\gamma\).
Some necessary and sufficient conditions characterizing radicals \(\gamma\) which are \(A\)-radicals are proved in this paper. These conditions are formulated in terms of the properties of quasi-ideals of rings \(A\in\gamma\).
