Abstract
Let and be complex Banach spaces with dimension at least three, and be standard operator algebras on and , respectively. For , let be a sequence with terms chosen from and assume that at least one of the terms in appears exactly once. Define the generalized Jordan product on elements in . This includes the usual Jordan product , and the Jordan triple . Let be a map with range containing all operators of rank at most three. It is shown that satisfies that for all , where stands for the peripheral spectrum of , if and only if is a Jordan isomorphism multiplied by an th root of unity.
