Some Bounds on the Energy of Graphs with Self-Loops regarding $λ_{1}$ and $λ_{n}$

Minghua Li, Yue Liu

Let $G_{S}$ be a graph with $n$ vertices obtained from a simple graph $G$ by attaching one self-loop at each vertex in $S \subseteq V (G)$ . The energy of $G_{S}$ is defined by Gutma…

Maximal signed bipartite graphs with totally disconnected graphs as star complements

Huiqun Jiang, Yue Liu

Let $B ˙ ≜ B ˙_{H ˙, μ}$ denote an arbitrary signed bipartite graph with $H ˙$ as a star complement for an eigenvalue $μ$ , where $\dot{H…
