Extremal spectral results of planar graphs without vertex-disjoint cycles

Longfei Fang, Huiqiu Lin, Yongtang Shi

Given a planar graph family $F$ , let $ex_{P} (n, F)$ and $spex_{P} (n, F)$ be the maximum size and maximum spectral radius…

Spectral extremal problem on $t$ copies of $ℓ$ -cycle

Longfei Fang, Mingqing Zhai, Huiqiu Lin

Denote by $t C_{ℓ}$ the disjoint union of $t$ cycles of length $ℓ$ . Let $e x (n, F)$ and $s p e x (n, F)$ be the maximum size and spectral radius over all $n$ -vertex $F$ -free graphs, re…
