On minimal extensions of rings

Rings and Algebras 2011-10-05 v1

Abstract

Given two rings RSR \subseteq S, SS is said to be a minimal ring extension of RR if RR is a maximal subring of SS. In this article, we study minimal extensions of an arbitrary ring RR, with particular focus on those possessing nonzero ideals that intersect RR trivially. We will also classify the minimal ring extensions of prime rings, generalizing results of Dobbs, Dobbs & Shapiro, and Ferrand & Olivier on commutative minimal extensions.
