On Spectra Of Variants Of The Corona Of Two Graphs And Some New Equienergetic Graphs
Discussiones Mathematicae Graph Theory, 2016 Let G and H be two graphs. The join G ∨ H is the graph obtained by joining every vertex of G with every vertex of H. The corona G ○ H is the graph obtained by taking one copy of G and |V (G)| copies of H and joining the i-th vertex of G to every vertex ...

Seidel Laplacian Energy of Fuzzy graphs
EAI Endorsed Transactions on Energy WebThe energy of a graph is related to its spectrum, which is equal to the total of the latent values of the pertinent adjacency matrix. In this research work, we proposed some of the features and the energy of the Seidel Laplacian of a fuzzy graph.

New Bounds for Distance Energy of A Graph [PDF]
Journal of the Indonesian Mathematical Society, 2020 For any connected graph G, the distance energy, E_D(G) is defined as the sum of the absolute eigenvalues of its distance matrix. Distance energy was introduced by Indulal et al in the year 2008. It has significant importance in QSPR analysis of molecular descriptor to study their physico-chemical properties.
