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) =\{…
Chromatic Schultz Polynomial of Certain Graphs
Sudev Naduvath
A topological index of a graph is a real number which is preserved under isomorphism. Extensive studies on certain polynomials related to these topological indices have also be…
Chromatic Topological Indices of Certain Cycle Related Graphs
Smitha Rose, Sudev Naduvath
Topological indices are real numbers invariant under graph isomorphisms. Chromatic analogue of topological indices has been introduced recently in literature in 2017. Mainly, chrom…
On -Colouring of Chithra Graphs
Johan Kok, Sudev Naduvath
The family of Chithra graphs is a wide ranging family of graphs which includes any graph of size at least one. Chithra graphs serve as a graph theoretical model for genetic enginee…
-Colouring of Cycle Related Graphs
Johan Kok, Sudev Naduvath
With respect to a proper colouring of a graph , we know that . If distinct colours represent distinct technology types to be located at vertices the…
