ECCENTRIC NEIGHBOURHOOD TOPOLOGICAL INDICES OF WHEEL RELATED GRAPHS

Abstract

Let G be a simple graph. The eccentricity e(v) of a vertex v is the maximum distance between v and any other vertex u in G. We denote S_{en}(u) =∑_(v∈N(u))▒E(v) be the eccentricity neighbourhood v∈N(u) degree of u. In this article, we found the formula to calculate some eccentric neighbourhood Topological indices of line graph, middle graph and total graph of wheel graph.
