The Hyper-Zagreb Index of Trees and Unicyclic Graphs

Hassan Rezapour, Ramin Nasiri, Seyedahmad Mousavi

Applications in chemistry motivated mathematicians to define different topological indices for different types of graphs. The Hyper-Zagreb index (HM) is an important tool as it int…

The Signless Laplacian Estrada Index of Unicyclic Graphs

Hamid Reza Ellahi, Ramin Nasiri, Gholam Hossein Fath-Tabar +1

For a graph $G$ , the signless Laplacian Estrada index is defined as $S L E E (G) = \sum_{i = 1}^{n} e^{q_{i}}$ ,where $q_{1}, q_{2}, \dots, q_{n}$ are the eigenvalues of the signless Laplacian mat…

The signless Laplacian Estrada index of tricyclic graphs

Ramin Nasiri, Hamid Reza Ellahi, Gholam Hossein Fath-Tabar +2

The signless Laplacian Estrada index of a graph $G$ is defined as $S L E E (G) = \sum_{i = 1}^{n} e^{q_{i}}$ where $q_{1}, q_{2}, \dots, q_{n}$ are the eigenvalues of the signless Laplacian matrix…

On Maximum Signless Laplacian Estrada Index of Graphs with Given Parameters II

Ramin Nasiri, Hamid Reza Ellahi, Gholam Hossein Fath-Tabar +1

Recently Ayyaswamy [1] have introduced a novel concept of the signless Laplacian Estrada index (after here $S L E E$ ) associated with a graph $G$ . After works, we have identified the…
