On the maximal index of $C_{4}^{-}$ -free unbalanced signed graphs of prescribed size

Zhihui Yang, Dan Li, Yuanyuan Chen

The extremal problem of determining the graphs with maximum spectral radius among all graphs with a prescribed number of edges was resolved by Rowlinson [Linear Algebra Appl. 110 (…

Spectral extremal problems on planar and outerplanar graphs without $C_{k,l}

Jiamin Li, Dan Li, Xilong Yin +1

Let $spex_{P} (n, F)$ and $spex_{O P} (n, F)$ be the maximum spectral radius among all $n$ -vertex $F$ -free planar graphs and outerplanar graphs, respec…

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)…
