Abstract

The Y-index of a graph is defined as the sum of degree four of all the vertices of the graph and HF-index is also called as the Forgotten Hyper index. In this chapter, we obtain the HF index of some graph operations such as join, Cartesian Product, Corona Product of graphs and Y-index of four operations (S,R,Q,T) of graphs related to the graphs join.
