Abstract
In this paper I-radicals are studied. Rings are characterized with the help of I-radicals. For example, each I-radical over a left perfect ring splits if and only if this ring is a direct sum of finitely many left perfect rings, the Jacobson radicals of which are maximal ideals of them.O. Horbachuk
