Certain Chromatic Sums of Some Cycle Related Graph Classes

N. K. Sudev, K. P. Chithra, Johan Kok

Let $C = {c_{1}, c_{2}, c_{3}, \dots, c_{k}}$ be a certain type of proper $k$ -colouring of a given graph $G$ and $θ (c_{i})$ denote the number of times a particular colour $c_{i}$ is…

On Chromatic Zagreb Indices of Certain Graphs

Johan Kok, N. K. Sudev, U. Mary

In this paper we introduce a variation of the well-known Zagreb indices by considering a proper vertex colouring of a graph $G$ . The chromatic Zagreb indices are defined in terms o…

A Note on the Tattoo Index of Graphs

Johan Kok, Naduvath Sudev

Consider a network $D$ of pipes which have to be cleaned using some cleaning agents, called brushes, assigned to some vertices. The tattooing of a simple connected directed graph $…
