Graphs determined by signless Laplacian spectra

Ali Zeydi Abdian, Afshin Behmaram, Gholam Hossein Fath-Tabar

In the past decades, graphs that are determined by their spectrum have received more attention, since they have been applied to several fields, such as randomized algorithms, combi…

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…
