Minimizers for the energy of eccentricity matrices of trees

Iswar Mahato, M. Rajesh Kannan

The eccentricity matrix of a connected graph $G$ , denoted by $E (G)$ , is obtained from the distance matrix of $G$ by keeping the largest nonzero entries in each row and ea…

Squared distance matrices of trees with matrix weights

Iswar Mahato, M. Rajesh Kannan

Let $T$ be a tree on $n$ vertices whose edge weights are positive definite matrices of order $s$ . The squared distance matrix of $T$ , denoted by $Δ$ , is the $n s \times n s$ block ma…

On the eccentricity matrices of trees: Inertia and spectral symmetry

Iswar Mahato, M. Rajesh Kannan

The \textit{eccentricity matrix} $E (G)$ of a connected graph $G$ is obtained from the distance matrix of $G$ by keeping the largest non-zero entries in each row and each…
