Isomorphisms of Birkhoff-James orthogonality on finite-dimensional C*-algebra
Abstract
We classify bijective maps which strongly preserve Birkhoff-James orthogonality on a finite-dimensional complex C*-algebra. It is shown that those maps are close to being real-linear isometries whose structure is also determined.
