Skew polynomial rings over abelian and idempotent reflexive rings

Abstract: Let $R$ be a ring and $\sigma$ an endomorphism of $R$. In this note, we study skew polynomial rings and skew power series rings over idempotent reflexive rings and abelian rings. Also, we introduce the concept of right (resp., left) $\sigma$-idempotent reflexive rings which generalizes right (resp., left) idempotent reflexive rings and $\sigma$-abelian rings. Certain results are obtained as corollaries from our results.
