Goldie conditions for Ore extensions over semiprime rings

Abstract

Let $R$ be a ring, $\sigma$ an injective endomorphism of $R$ and $\delta$ a $\sigma$-derivation of $R$. We prove that if $R$ is semiprime left Goldie then the same holds for the Ore extension $R[x;\sigma ,\delta ]$ and both rings have the same left uniform dimension.
