چکیده
|
The energy of a graph 𝐺, denoted by 𝐸(𝐺), is defined as the sum of the absolute values of all eigenvalues of 𝐺. in this paper, lower and upper bounds for energy in some of the graphs are established, in terms of graph invariants such as the number of vertices, the number of edges, and the number of closed walks.
