Abstract:

Let be the real Jordan algebra of all self- adjoint operators on a complex Hilbert space.We characterize the surjective maps preserving the -numerical radius of products for operators in.Further, for a special kind of,the form of surjections preserving the -numerical range of products for operators in is obtained.
