Schultz and Zagreb Indices in Corona of two Graphs

Abstract

The $corona$ of two graphs $G$ and $H$, written as $G\odot H$, is defined as the graph obtained by taking one copy of $G$ and $|V(G)|$ copies of $H$, and joining by an edge the $i$th vertex of $G$ to every vertex in the $i$th copy of $H$. In this paper, we present the explicit formulae of the (modified) Schultz and Zagreb indices in the corona of two graphs.
