### A Study on the Sparing Number of the Corona of Certain Graphs

#### Abstract

*Let ** be the set of all non-negative integers and ** be its the power set. An integer additive set-indexer (IASI) is defined as an injective function ** such that the induced function ** defined by ** is also injective, where ** is the sum set of ** and **. If **, then ** is said to be a **-uniform integer additive set-indexer. An integer additive set-indexer ** is said to be a weak integer additive set-indexer if **. We have some characteristics of the graphs which admit weak integer additive set-indexers. In this paper, we study about the sparing number of the corona of two graphs. *
