Objectives: The objective of this paper is to find exact proper d-lucky number for corona product graphs of certain graphs. Methods: The results are proved by method of elaboration and construction. Findings: Exact proper d-lucky numbers are obtained for corona products: Pn⊙ Cm, Pn⊙ Km,Cn⊙ Kn and Kn⊙ Kn. Novelty: Proper d-lucky labeling for the corona product of Pn⊙Cm, Pn⊙ Km, Cn⊙ Kn and Kn⊙ Kn are not studied by any other authors, thus the proper dlucky numbers for the above graphs are new findings.
Keywords: Lucky labeling; Proper labeling; d-lucky labeling; Proper d-lucky labeling; Corona product
