On Certain Topological Indices of Signed Graphs
Sudev Naduvath, Johan Kok
The first Zagreb index of a graph is the sum of squares of the vertex degrees in a graph and the second Zagreb index of is the sum of products of degrees of adjacent vertic…
On Derivative Euler Phi Function Set-Graphs
Johan Kok, Eunice Gogo Mphako-Banda, Sudev Naduvath
In this paper, we study some graph theoretical properties of two derivative Euler Phi function set-graphs. For the Euler Phi function , , the set $S_ϕ(n) =\{…
On Certain Colouring Parameters of Graphs
N. K. Sudev, S. Satheesh, K. P. Chithra +1
Colouring the vertices of a graph according to certain conditions can be considered as a random experiment and a discrete random variable can be defined as the number of ve…
Chromatic Zagreb indices for graphical embodiment of colour clusters
Johan Kok, Naduvath Sudev, Muhammad Kamran Jamil
For a colour cluster , where is a colour class such that , a…
A Study on the Quadratic Jaco Graph
R. Jayasree, A. Kulandai Therese, U. Mary +1
In this paper we introduce the quadratic Jaco graph. The characteristics, properties and some graph invariants of quadratic Jaco graphs are discussed. The observation that quadrati…
A Study on Clique Invariants of Jaco-type Graphs
M. Jerlin Seles, U. Mary, Johan Kok
The first study related to this paper was on the notion of primitive holes. This paper reports on research in respect of clique parameters and related properties thereof within Jac…
