摘要：A graph with vertex set V is said to have a prime labeling if its vertices are labeled with distinct integers1,2,3 … 𝑉 such that for edge 𝑥𝑦 the labels assigned to x and y are relatively prime. A graph which admits primelabeling is called a prime graph. In this paper we investigate prime labeling for some helm related graphs. We alsodiscuss prime labeling in the context of some graph operations namely fusion and duplication in Helm 𝐻𝑛
