Adjacency and coherency preservers
Abstract: Two matrices are said to be adjacent if their difference is of
rank one. Fundamental theorems of geometry of matrices proved by L.-K.
Hua describe the general form of bijective maps on various spaces of
matrices preserving adjacency in both directions. We will present
several recent improvements of these results and some applications in
mathematical physics.
