Commutativity via Spectral Equivalences of the Jordan Product in Banach Algebras
Muhammad Hassen
Spectral characterizations of algebraic structure have a long history in the theory of Banach algebras. It is known that weak spectral information may force strong algebraic conseq…

The Multiplicative Kowalski-Slodkowski Theorem for Hermitian Algebras
Rudi Brits, Muhammad Hassen, Cheick Toure
We prove, for Hermitian algebras, the multiplicative version of the Kowalski-Słodkowski Theorem which identifies the characters among the collection of all complex valued functions…
