Abstract: Let be a Banach algebra over the complex field A mapping on is called an involution in case , holds for all and all A Banach algebra equipped with an involution is called Banach algebra with involution. A Banach algebra with involution is algebra in case holds for all algebras are important class of Banach algebras. Vidav-Palmer theorem characterizes algebras among all Banach algebras.
