Skew Randić Matrix and Skew Randić Energy

Ran Gu, Fei Huang, Xueliang Li

Let $G$ be a simple graph with an orientation $σ$ , which assigns to each edge a direction so that $G^{σ}$ becomes a directed graph. $G$ is said to be the underlying graph of the dire…

Randić Incidence Energy of Graphs

Ran Gu, Fei Huang, Xueliang Li

Let $G$ be a simple graph with vertex set $V (G) = {v_{1}, v_{2}, \dots, v_{n}}$ and edge set $E (G) = {e_{1}, e_{2}, \dots, e_{m}}$ . Similar to the Randić matrix, here we introduce the Rand…

On maximum Estrada indices of bipartite graphs with some given parameters

Fei Huang, Xueliang Li, Shujing Wang

The Estrada index of a graph $G$ is defined as $E E (G) = \sum_{i = 1}^{n} e^{λ_{i}}$ , where $λ_{1},$ $λ_{2}, \dots, λ_{n}$ are the eigenvalues of the adjacency matrix of $G$ . In this paper, we ch…
