A vertex degree based topological index called the Sombor index was recently defined in 2021 by Gutman and has been very popular amongst chemists and mathematicians. We determine the amount of change of the Sombor index when some elements are removed

Molecules can be modelled by graphs to obtain their required properties by means of only mathematical methods and formulae. In this paper, several degree-based graph indices of one of the important chemical compounds called as polyester are calculate

The symmetric figure of a molecule and the fact that the bond polarities are equal imply that the polarities of the bonds cancel each other out and the molecule would be nonpolar. Many molecules are nonpolar, but have polar bonds. A chemical bond is

Derived graphs are the graphs obtained by some kind of operation on a given and usually smaller graph. By studying the relations between a graph and its derived graph, one can obtain information on one depending on the information on the other. In th
