Unitary automorphisms of the space of Toeplitz-plus-Hankel matrices
Our motivation was a paper of 1991 indicating three special unitary matrices that map Hermitian Toeplitz matrices by similarity into real Toeplitz-plus-Hankel matrices. Generalizing this result, we give a complete description of unitary similarity automorphisms of the space of Toeplitz-plus-Hankel...

Summary: | Our motivation was a paper of 1991 indicating three special unitary matrices that map Hermitian
Toeplitz matrices by similarity into real Toeplitz-plus-Hankel matrices. Generalizing this result, we give a
complete description of unitary similarity automorphisms of the space of Toeplitz-plus-Hankel matrices. |
