Spectral isometries on non-simple \(C^*\)-algebras (English)
0 references
A map between two complex unital Banach algebras is called a spectral isometry if it is linear and preserves the spectral radius. In the paper under review, the authors establish some permanence facts about spectral isometries and show that a unital surjective spectral isometry between certain non-simple unital \(C^*\)-algebras is a Jordan isomorphism.
