A Lower Bound for the Distance Laplacian Spectral Radius of Bipartite Graphs with Given Diameter
نویسندگان
چکیده
Let G be a connected, undirected and simple graph. The distance Laplacian matrix L(G) is defined as L(G)=diag(Tr)−D(G), where D(G) denotes the of diag(Tr) diagonal vertex transmissions. Denote by ρL(G) spectral radius G. In this paper, we determine lower bound n-vertex bipartite graphs with diameter 4. We characterize extremal attaining bound.

متن کاملThe minimal spectral radius of graphs with a given diameter
The spectral radius of a graph (i.e., the largest eigenvalue of its corresponding adjacency matrix) plays an important role in modeling virus propagation in networks. In fact, the smaller the spectral radius, the larger the robustness of a network against the spread of viruses. Among all connected graphs on n nodes the pathPn has minimal spectral radius. However, its diameter D, i.e., the maxim...
متن کاملThe Laplacian spectral radius of graphs with given matching number
In this paper, we show that of all graphs of order n with matching number β, the graphs with maximal spectral radius are Kn if n = 2β or 2β + 1; K2β+1 ∪Kn−2β−1 if 2β + 2 n < 3β + 2; Kβ ∨ Kn−β or K2β+1 ∪Kn−2β−1 if n = 3β + 2; Kβ ∨ Kn−β if n > 3β + 2, where Kt is the empty graph on t vertices. © 2006 Elsevier Inc.

متن کاملA lower bound for the spectral radius of graphs with fixed diameter
We determine a lower bound for the spectral radius of a graph in terms of the number of vertices and the diameter of the graph. For the specific case of graphs with diameter three we give a slightly better bound. We also construct families of graphs with small spectral radius, thus obtaining asymptotic results showing that the bound is of the right order. We also relate these results to the ext...
