Abstrakt:
The energy of a graph G, E(G), is the sum of absolute values of the eigenvalues of its adjacency matrix. This concept was first introduced by Gutman in 1978. In this talk, we try to present some lower and upper bounds for the energy of graphs and present their structural and spectral properties and also present some open conjectures in this area.
