On the Randić energy of caterpillar graphs

Domingos M. Cardoso, Paula Carvalho, Roberto C. Díaz +1

A caterpillar graph $T (p_{1}, \dots, p_{r})$ of order $n = r + \sum_{i = 1}^{r} p_{i}$ , $r \geq 2$ , is a tree such that removing all its pendent vertices gives rise to a path of order $r$ . In t…

The H-join of arbitrary families of graphs

Domingos M. Cardoso, Helena Gomes, Sofia J. Pinheiro

The $H$ -join of a family of graphs $G = {G_{1}, \dots, G_{p}}$ , also called the generalized composition, $H [G_{1}, \dots, G_{p}]$ , where all graphs are undirected, simple and fin…
