Linear maps on $M_{n} (R)$ preserving Schur stable matrices

Chandrashekaran Arumugasamy, Sachindranath Jayaraman

An $n \times n$ matrix $A$ with real entries is said to be Schur stable if all the eigenvalues of $A$ are inside the open unit disc. We investigate the structure of linear maps on…

A characterization of nonnegativity relative to proper cones

Chandrashekaran Arumugasamy, Sachindranath Jayaraman, Vatsalkumar N. Mer

Let $A$ be an $m \times n$ matrix with real entries. Given two proper cones $K_{1}$ and $K_{2}$ in $R^{n}$ and $R^{m}$ , respectively, we say that $A$ is nonnegative if $A…
