Ordering of bicyclic graphs by matching energy

Xiangxiang Liu, Ligong Wang, Peng Xiao

Let $G$ be a simple graph of order $n$ and $μ_{1}, μ_{2}, \dots, μ_{n}$ be the roots of its matching polynomial. The matching energy is defined as the sum $\sum_{i = 1}^{n} ∣ μ_{i} ∣$ , wh…

Edge Connectivity, Packing Spanning Trees, and Eigenvalues of Graphs

Cunxiang Duan, Ligong Wang, Xiangxiang Liu

Let $G$ be the set of simple graphs (or multigraphs) $G$ such that for each $G \in G$ there exists at least two non-empty disjoint proper subsets $V_{1},V_{2}\s…
