Generalizations of Reversible and Symmetric Rings

Abstract

In this thesis we study central reversible and central symmetric rings, which are generalizations of reversible and symmetric rings respectively. We study their main characterizations and properties and its relationship with other classes of rings. Moreover, many ring extensions of those rings are considered. We introduce new classes of rings which are central  reversible and central  symmetric rings as a generalizations of reversible and  symmetric rings respectively, some results in this case were introduced.
