摘要
The distance spectral radius of a connected graph G, denoted by rho(G), is the maximal eigenvalue of the distance matrix of G. In this paper we find a sharp lower bound as well as a sharp upper bound of rho(G) in terms of omega(G), the clique number of G. Furthermore, both extremal graphs are unique decided.
