Eigenvalues of signed graphs

Dan Li, Huiqiu Lin, Jixiang Meng

Signed graphs have their edges labeled either as positive or negative. $ρ (M)$ denote the $M$ -spectral radius of $Σ$ , where $M = M (Σ)$ is a real symmetric graph matrix of $Σ$ . Obvious…

The $A_{α}$ -spectral radius of graphs with given degree sequence

Dan Li, Yuanyuan Chen, Jixiang Meng

Let $G$ be a graph with adjacency matrix $A (G)$ , and let $D (G)$ be the diagonal matrix of the degrees of $G$ . For any real $α \in [0, 1]$ , write $A_{α} (G)$ for the matrix $$A_α(G)=αD(G)…
