Harmonic Index and Harmonic Polynomial on Graph Operations

Harmonic Index and Harmonic Polynomial on Graph Operations

Some years ago, the harmonic polynomial was introduced to study the harmonic topological index. Here, using this polynomial, we obtain several properties of the harmonic index of many classical symmetric operations of graphs: Cartesian product, corona product, join, Cartesian sum and lexicographic p...
