Operators preserving the strong Birkhoff-James orthogonality on B(H)
We characterize the class of surjective (conjugate) linear mappings from B(H) to B(H) that preserve the strong Birkhoff-James orthogonality in both directions. We also give characterizations of rank-one operators as well as coisometries in terms of the strong Birkhoff-James orthogonality.
