Streszczenie
We study Ore extensions of non-unital associative rings. We provide a characterization of simple non-unital differential polynomial rings , under the hypothesis that R is s-unital and \ker (\delta ) contains a non-zero idempotent. This result generalizes a result by Öinert, Richter and Silvestrov from the unital setting. We also present a family of examples of simple non-unital differential polynomial rings.
