Proofs of Li, Wang and Guo's conjectures on (signless) Laplacian spectral radius

Hongzhang Chen, Jianxi Li, Xiaoyun Lv

Let $\mu (G)$ and $q(G)$ be the Laplacian and signless Laplacian spectral radii of a graph $G$. Li, Wang and Guo (2026) conjectured that, if $H$ with $|V(H)|\ge 1$ is an induced subg…
