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

Mingqing Zhai, Huiqiu Lin, Shicai Gong

Let $G$ be a graph with $n$ vertices and $λ_{n} (G)$ be the least eigenvalue of its adjacency matrix of $G$ . In this paper, we give sharp bounds on the least eigenvalue of graphs with…

On the determinant of the distance matrix of a bicyclic graph

Shi-Cai Gong, Ju-Li Zhang, Guang-Hui Xu

Two cycles are referred as disjoint if they have no common edges. In this paper, we will investigate the determinant of the distance matrix of a graph, giving a formula for the det…

On oriented graphs with minimal skew energy

Shicai Gong, Xueliang Li, Guanghui Xu

Let $S (G^{σ})$ be the skew-adjacency matrix of an oriented graph $G^{σ}$ . The skew energy of $G^{σ}$ is defined as the sum of all singular values of its skew-adjacency matrix $S (G^{σ})$ . I…
