Let G=(V, E), V={v1, v2,..., vn}, be a simple graph without isolated vertices, with the sequence
of vertex degrees d1≥ d2≥...≥ dn> 0, di= d (vi). If vertices vi and vj are adjacent in G, we …

We show how Schwitzer inequality allows us to find inequalities relating an additive
descriptor of the form Dp (G)=∑ N i= 1 cp i to its reciprocal D− p (G)=∑ N i= 1 c− p i. We look …

A molecular graph or a chemical graph is a graph related to the structure of a chemical
compound. The topological indices play a vital role in understanding the physical, chemical …

There are several classes of anticancer drugs, among which our study focuses on alkylating
agents. As a chemical graph invariant number, topological index, has crucial role in …

B vitamins are crucial for the proper functioning of our body. Vitamin B complex, comprising
eight essential vitamins, supports growth and sustains energy levels. Graph theory aids …
