RT journal article T1 Structure of non-unital purely infinite simple rings A1 González-Barroso, M.A. A1 Pardo Espino, Enrique A2 Matemáticas AB In this note, we study the notion of purely infinite simple ring in the case of nonunital rings, and we obtain an analog to Zhang's Dichotomy for σ-unital purely infinite simple C*-algebras in the purely algebraic context.
