Abstract
We completely describe surjective maps preserving the peripheral local spectrum of Jordan product of operators. Let \(x_0 \in X\) and \(y_0 \in Y \) be two nonzero vectors. We show that a map \(\varphi \) from B(X) onto B(Y) satisfies
if and only if there exists a bijective bounded linear map from X into Y such that\( A(x_0)=y_0\) and either \(\varphi (T)=-ATA^{-1}\) for all \(T \in B(X) \) or \(\varphi (T)=ATA^{-1}\) for all \(T \in B(X)\).
