Spanning k-trees and distance spectral radius in graphs

Journal of Supercomputing, 2023
Let $k\geq2$ be an integer. A tree $T$ is called a $k$-tree if $d_T(v)\leq k$ for each $v\in V(T)$, that is, the maximum degree of a $k$-tree is at most $k$.

On the spectral radius and the energy of eccentricity matrices of graphs

Linear and multilinear algebra, 2021
The eccentricity matrix of a connected graph G is obtained from the distance matrix of G by retaining the largest distance in each row and each column and setting the remaining entries as 0.

A note on the ABC spectral radius of graphs

Linear and multilinear algebra, 2020
The ABC matrix of a graph G, recently introduced by Estrada, is the square matrix of order whose -entry is if the ith vertex and the jth vertex of G are adjacent, and 0 otherwise, where is the degree of the ith vertex of G.
