On the maximum $A_{α}$ -spectral radius of unicyclic and bicyclic graphs with fixed girth or fixed number of pendant vertices

Joyentanuj Das, Iswar Mahato

For a connected graph $G$ , let $A (G)$ be the adjacency matrix of $G$ and $D (G)$ be the diagonal matrix of the degrees of the vertices in $G$ . The $A_{α}$ -matrix of $G$ is defined as…

A note on the distance and distance signless Laplacian spectral radius of complements of trees

Iswar Mahato, M. Rajesh Kannan

In this article, we show that the generalized tree shift operation increases the distance spectral radius, distance signless Laplacian spectral radius, and the $D_{α}$ -spectral radiu…

Extremal problems for the eccentricity matrices of complements 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…
