Abstract
In this paper we present k-cordiality of one point union of some path, cycle and star related graphs. We prove that bistar graph Bm,n is k-cordial for all k, restricted square graph B2n,n of Bistar is k-cordial for all k. We also prove that one point union of cycle C3 with star graph K1,n and one point union of path Pn with K1 are k-cordial for all k.
Keywords: Abelian group, k-cordial labeling, bistar, comb, one point union.
