Square difference labeling of some union and disjoint union graphs

Zoya Sherman

Abstract


The paper deals with methods of constructing square difference labeling of caterpillars and graphs derived from two operations: path union of cycles and disjoint union of stars. The existence of the square difference labeling of disjoint union of any \(\mathrm{SD}\) graph with path is proved.
