Ulagammal, S.Vivin, Vernold J.2024-11-212024-11-212022-06-012075-7905https://doi.org/10.47013/15.2.6https://hdl.handle.net/11452/48259A star coloring of a graph G is a proper vertex coloring with the condition that no path on four vertices in G can be labelled by two colors. The star chromatic number chi(s) (G) of G is the least number of colors that is required to star color G. In this paper, we determine the star chromatic number of the degree splitting graph of the Cartesian product of any two simple graphs G and H denoted by G square H and also we portray the star chromatic number for the degree splitting graph of the Cartesian product of prism graphs, toroidal graphs and grid graphs.eninfo:eu-repo/semantics/closedAccessStar coloringCartesian productDegree splittingScience & technologyPhysical sciencesMathematicsArticle00082337660000624325415210.47013/15.2.6
