The $(k, ℓ)$ -rainbow index for complete bipartite and multipartite graphs

Qingqiong Cai, Xueliang Li, Jiangli Song

A tree in an edge-colored graph $G$ is said to be a rainbow tree if no two edges on the tree share the same color. Given two positive integers $k$ , $ℓ$ with $k \geq 3$ , the \emph…

New skew Laplacian energy of a simple digraph

Qingqiong Cai, Xueliang Li, Jiangli Song

For a simple digraph $G$ of order $n$ with vertex set ${v_{1}, v_{2}, \dots, v_{n}}$ , let $d_{i}^{+}$ and $d_{i}^{-}$ denote the out-degree and in-degree of a vertex $v_{i}$ in $G$ , respectively.…
