A Vertex-Localized Positive Square-Energy Strengthening of Turán's Theorem

Let $G$ be a graph of order $n$ with the adjacency eigenvalues $λ_1(G) \geq \dots \geq λ_n(G) $. Let $c(v)$ denote the maximum order of a clique containing vertex $v$. We prove the vertex-localized positive square-energy inequality \[ \sqrt{s_+(G)} \leq \sum_{v\in V}\left(1-\frac1{c(v)}\right)
