Distance spectral radius of a tree with given diameter

Guanglong Yu, Shuguang Guo, Mingqing Zhai

For a connected graph, the distance spectral radius is the largest eigenvalue of its distance matrix. In this paper, of all trees with both given order and fixed diameter, the tree…

Spectral conditions for the existence of specified paths and cycles in graphs

Mingqing Zhai, Huiqiu Lin, Shicai Gong

Let be a graph with vertices and be the least eigenvalue of its adjacency matrix of . In this paper, we give sharp bounds on the least eigenvalue of graphs with…
