Variants of spectral Turán theorems and eigenvectors of graphs

Lele Liu, Bo Ning

In 2002, Nikiforov proved that for an $n$ -vertex graph $G$ with clique number $ω$ and edge number $m$ , the spectral radius $λ (G)$ satisfies $λ (G) \leq 2 (1 - 1/ ω) m$ , which c…

Rainbow triangles sharing one common vertex or edge

Xiaozheng Chen, Bo Ning

Let $G$ be an edge-colored graph on $n$ vertices. For a vertex $v$ , the \emph{color degree} of $v$ in $G$ , denoted by $d^{c} (v)$ , is the number of colors appearing on the edges incid…
