Maximum values of the Sombor-index-like graph invariants of trees and connected graphs

open access: yes
A set of novel vertex-degree-based invariants was introduced by Gutman, denoted by \newline $SO_1, SO_2, \ldots,SO_6$. These invariants were constructed through geometric reasoning based on a new graph invariant framework.

On vertex peripherians and Wiener index of graphs with fixed number of cut vertices

open access: yes
The distance of a vertex in a graph is the sum of distances from that vertex to all other vertices of the graph. The Wiener index of a graph is the sum of distances between all its unordered pairs of vertices.
