CHARACTERIZATIONS OF C*-ALGEBRAS.
Abstract
A Banach algebra is a C*-algebra iff each element can be expressed as R + iJ where R and J have real numerical range. A Banach algebra with an involution is a C*-algebra iff the closed convex hull of (e to the power (iR): R = R*) is the closed unit ball. (Author)
