Resumen de Jordan isomorphism of purely infinite C*-algebras
Ying-Fen Lin, Martin Mathieu 
We prove that every unital bounded linear mapping from a unital purely infinite C*-algebra of real rank zero into a unital Banach algebra which preserves elements of square zero is a Jordan homomorphism. This entails a description of unital surjective spectral isometries as the Jordan isomorphisms in this setting.
