چکیده مقاله
The modified Sombor (mSO) index of a given graph G is symbolized with mSO and define by sum of the weights (Formula presented), where du is the degree of a vertex u in G. In this work, we present the first and second maximum values of the mSO index among all n-vertex c-cyclic graphs. We also provide that the mSO index attains its maximum and second maximum on two classes of chemical graphs. Finally, we will present new lower and upper bounds for the mSO index of connected chemical graphs. © 2025 World Scientific Publishing Company.
