Dynamics of Products of Matrices in Max Algebra

S. Jayaraman, Y. K. Prajapaty, S. Sridharan

The aim of this manuscript is to understand the dynamics of matrix products in a max algebra. A consequence of the Perron-Fröbenius theorem on periodic points of a nonnegative matr…

Dynamics of products of nonnegative matrices

Sachindranath Jayaraman, Yogesh Kumar Prajapaty, Shrihari Sridharan

The aim of this manuscript is to understand the dynamics of products of nonnegative matrices. We extend a well known consequence of the Perron-Frobenius theorem on the periodic poi…

On linear preservers of semipositive matrices

Sachindranath Jayaraman, Vatsalkumar N. Mer

Given proper cones $K_{1}$ and $K_{2}$ in $R^{n}$ and $R^{m}$ , respectively, an $m \times n$ matrix $A$ with real entries is said to be semipositive if there exists a $x…

Distance Matrix of a Class of Completely Positive Graphs: Determinant and Inverse

Joyentanuj Das, Sachindranath Jayaraman, Sumit Mohanty

A real symmetric matrix $A$ is said to be completely positive if it can be written as $B B^{t}$ for some (not necessarily square) nonnegative matrix $B$ . A simple graph $G$ is called…

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…
