The first entire Zagreb index of various corona products and their bounds
Abstract
The First Entire Zagreb Index (FEZI) of a (molecular) graph was introduced by Alwardi et al. [2] as the sum of the squares of degree of all the vertices and edges of the given graph. In this paper, the exact expressions for the FEZI of two graphs of several types of Corona products are established. Finally, the obtained results are applied to compute the bounds for the FEZI of two graphs.
