A note on eigenvalues and Hamiltoinan properties of $k$ -connected graphs

Huicai Jia, Ruifang Liu, Hong-Jian Lai

Let $λ_{1} (G)$ and $μ_{1} (G)$ denote the spectral radius and the Laplacian spectral radius of a graph $G$ , respectively. Li in [Electronic J. Linear Algebra 34 (2018) 389-392] prov…

Spanning tree packing, edge-connectivity and eigenvalues of graphs with given girth

Ruifang Liu, Hong-Jian Lai, Yingzhi Tian

Let $τ (G)$ and $κ^{'} (G)$ denote the edge-connectivity and the spanning tree packing number of a graph $G$ , respectively. Proving a conjecture initiated by Cioaba and Wong, Liu et al.…
