Published online by Cambridge University Press: 21 November 2014
Abstract
For a positive integer $n\geq 2$, let
$M_{n}$ be the set of
$n\times n$ complex matrices and
$H_{n}$ the set of Hermitian matrices in
$M_{n}$. We characterize injective linear maps
${\it\phi}:H_{m_{1}\cdots m_{l}}\rightarrow H_{n}$ satisfying
