Characterizes linear preservers of rank one matrices and determinants for Toeplitz matrices.
We study linear preserver problems on the linear space of n × n n × n Toeplitz matrices over the real field or the complex field. In particular, characterizations are given for linear preservers of rank one matrices and linear preservers of the determinant. We also present related results and questions on other structured matrices.
