Spectral extremal graphs for the bowtie

Yongtao Li, Lu Lu, Yuejian Peng

Let $F_{k}$ be the (friendship) graph obtained from $k$ triangles by sharing a common vertex. The $F_{k}$ -free graphs of order $n$ which attain the maximal spectral radius was firstly…

Spectral radius of graphs forbidden $C_{7}$ or $C_{6}^{△}$

Junying Lu, Lu Lu, Yongtao Li

Let $C_{k}^{△}$ be the graph obtained from a cycle $C_{k}$ by adding a new vertex connecting two adjacent vertices in $C_{k}$ . In this note, we obtain the graph maximizing th…
