Abstract:A linear mappingTTfrom a subspaceEEof a Banach algebra into another Banach algebra is called spectrally bounded if there is a constantM≥0M\geq 0such thatr(Tx)≤Mr(x)r(Tx)\leq M\,r(x)for allx∈Ex\in E, wherer(⋅)r(\,\cdot \,)denotes the spectral radius. We prove that every spectrally bounded unital operator from a unital purely infinite simpleC∗C^*-algebra onto a unital semisimple Banach algebra is a Jordan epimorphism.
