© 2017. Miskolc University Press.In this paper we introduce a class of quasipolar rings which is a generalization of J - quasipolar rings. Let R be a ring with identity. An element a ∈ R is called δ-quasipolar if there exists p2 = p ∈ comm2(a) such that a + p is contained in δ(R), and the ring R is called δ-quasipolar if every element of R is δ-quasipolar. We use δ-quasipolar rings to extend some results of J-quasipolar rings. Then some of the main results of J-quasipolar rings are special cases of our results for this general setting. We give many characterizations and investigate general properties of δ-quasipolar rings.
