Cayley transform and the Kronecker product of Hermitian matrices

Yorick Hardy, Ajda Fošner, Willi-Hans Steeb

We consider the conditions under which the Cayley transform of the Kronecker product of two Hermitian matrices can be again presented as a Kronecker product of two matrices and, if…

Linear maps preserving numerical radius of tensor product of matrices

Ajda Fošner, Zejun Huang, Chi-Kwong Li +1

We determine the structure of linear maps on the tensor product of matrices which preserve the numerical range or numerical radius.
