Spectral extremal problem on the square of -cycle
Longfei Fang, Yanhua Zhao
Let be the cycle of order . The square of , denoted by , is obtained by joining all pairs of vertices with distance no more than two in $C_…
A spectral condition for the existence of cycles with consecutive odd lengths in non-bipartite graphs
Zhiyuan Zhang, Yanhua Zhao
A graph is called -free, if it does not contain as a subgraph. In 2010, Nikiforov proposed a Brualdi-Solheid-Turán type problem: what is the maximum spectral radius of a…
Spectral radius, edge-disjoint cycles and cycles of the same length
Huiqiu Lin, Mingqing Zhai, Yanhua Zhao
In this paper, we give spectral conditions to guarantee the existence of two edge disjoint cycles and two cycles of the same length. These two results can be seen as spectral analo…
The signless Laplacian spectral radius of graphs with no intersecting triangles
Yanhua Zhao, Xueyi Huang, Hangtian Guo
Let denote the -fan consisting of triangles which intersect in exactly one common vertex, and the complete split graph of order consisting of a clique on…
The maximum spectral radius of wheel-free graphs
Yanhua Zhao, Xueyi Huang, Huiqiu Lin
A wheel graph is a graph formed by connecting a single vertex to all vertices of a cycle. A graph is called wheel-free if it does not contain any wheel graph as a subgraph. In 2010…
The -spectral radius and perfect matchings of graphs
Yanhua Zhao, Xueyi Huang, Zhiwen Wang
Let , and let be a graph of even order with , where for , for and for . I…
