@Article{, title={On Harmonic Index Some Special Graphs with Certain Vertex Gluing Graphs}, author={Haneen Kareem Aljanabi}, journal={Journal of Kufa for Mathematics and Computer مجلة الكوفة للرياضيات والحاسوب}, volume={5}, number={2}, pages={6-12}, year={2018}, abstract={The stability of cycloalkanes strain energy, branched alkanes and linear alkanes, can be reasonablymodeled using the harmonic index (H), which is commonly defined as H(G)Σ where d(u) denotes thevertex degree of u in graph G. In the current work, public equation is derived to the H index of vertex gluing andcertain graphs.
