On bipartite graphs having minimal fourth adjacency coefficient

Shi Cai Gong, Shao Wei Sun

Let $G$ be a simple graph with order $n$ and adjacency matrix $A (G)$ . Let $ϕ (G; λ) = det (λ I - A (G)) = \sum_{i = 0}^{n} a_{i} (G) λ^{n - i}$ be the characteristic polynom…

On graphs having minimal fourth adjacency coefficient

Shi Cai Gong, Shi Wei Sun

Let $G$ be a graph with order $n$ and adjacency matrix $A (G)$ . The adjacency polynomial of $G$ is defined as $ϕ(G;λ) =det(λ\mathbf{I}-\mathbf{A}(G))=\sum_{i=0}^n\mathbf{a_…
