Estrada Index of Bipartite Graphs

2008
Let be a simple graph with vertices and let be its eigenvalues. The Estrada index of is We present some lower and upper bounds for of a bipartite graph in terms of graph invariants such as the number of vertices, the number of edges, the largest eigenvalue, the spectral moments and the first Zagreb index.
