Skew-rank of an oriented graph in terms of the rank and dimension of cycle space of its underlying graph

Yong Lu, Ligong Wang, Qiannan Zhou

Let $G^{σ}$ be an oriented graph and $S (G^{σ})$ be its skew-adjacency matrix, where $G$ is called the underlying graph of $G^{σ}$ . The skew-rank of $G^{σ}$ , denoted by $sr (G^{σ})$ , is the ra…

Distance signless Laplacian spectral radius and Hamiltonian properties of graphs

Qiannan Zhou, Ligong Wang

In this paper, first, we establish a sufficient condition for a bipartite graph to be Hamilton-connected. Furthermore, we also give two sufficient conditions on distance signless L…
