dc.description.abstractThis research work deals with commutativity theorems for rings and near-rings with their various generalizations in the setting of some special classes of rings as well as derivations in rings and near-rings. We present their fundamentals and also prove some commutativity results for semi prime rings and ring with unity.We then extended the results to s-unital rings. Some results on commutativity of rings and near-rings are generalized and justified by examples. Posner‟s first theorem isestablished for 𝜎−prime rings. Jordan left and right 𝜎−derivations as well as generalized Jordan left and right 𝜎−derivations on 𝜎−rings are investigated. Further more,distributive near-ring, pseudo-abelian near-ring and distributively generated near-rings are introduced andthese help in developing certain class of derivations on near-rings. Finally, permuting 4−(𝜎,𝜏) derivations on prime near-rings are generalized to permuting 𝑛−(𝜎,𝜏) derivations.en_US
