Set-Valuations of Graphs and their Applications: A Survey

A set-valuation of a graph G = (V, E) assigns to the vertices or edges of G elements of the power set X 2 of a given nonempty set X subject to certain conditions and set-valuations have a variety of origins. Acharya defined a set-indexer of G to be an injective set-valuation X G V f 2 ) ( : → such that the induced set-valuation ) ( : G E f ⊕ X 2 → on the edges of G defined by ) ( ), ( ) ( ) ( G...

Chromatic Harmonic Indices and Chromatic Harmonic Polynomials of Certain Graphs

In the main this paper introduces the concept of chromatic harmonic polynomials denoted, $H^chi(G,x)$ and chromatic harmonic indices denoted, $H^chi(G)$ of a graph $G$. The new concept is then applied to finding explicit formula for the minimum (maximum) chromatic harmonic polynomials and the minimum (maximum) chromatic harmonic index of certain graphs. It is also applied to split graphs and ce...

CERTAIN TYPES OF EDGE m-POLAR FUZZY GRAPHS

In this research paper, we present a novel frame work for handling $m$-polar information by combining the theory of $m-$polar fuzzy  sets with graphs. We introduce certain types of edge regular $m-$polar fuzzy graphs and edge irregular $m-$polar fuzzy graphs. We describe some useful properties of edge regular, strongly edge irregular and strongly edge totally irregular $m-$polar fuzzy graphs. W...
