Spectral extremal results on the -index of graphs without minors and star forests
Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang
Let be a graph of order , and let and be the adjacency matrix and the degree matrix of respectively. Define the convex linear combinations of $A (…
The signless Laplacian spectral radius of graphs without intersecting odd cycles
Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang
Let be a graph consisting of cycles of odd length , respectively which intersect in exactly a common vertex, where and $a_1\g…
On the spectral radius of graphs without a star forest
Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang
In this paper, we present two sharp upper bounds for the spectral radius of (bipartite) graphs with forbidden a star forest and characterize all extremal graphs. Moreover, the mini…
The signless Laplacian spectral radius of graphs with forbidding linear forests
Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang
Turán type extremal problem is how to maximize the number of edges over all graphs which do not contain fixed forbidden subgraphs. Similarly, spectral Turán type extremal problem i…
