Integer Cordial Labeling in context of Ring sum of Graphs
Abstract: An Integer Cordial Labeling of a graph G*(p, q) is an one-one map g: V * or as p is even or odd, which induces an edge labeling defined by such that the number of edges labeled 1 and the number of edges labeled 0 differ by at most 1. If a graph has integer cordial labeling (I.C.L.), then it is called integer cordial graph (I.C.G.). In this paper, I …

3-Equitable Labeling in Context of Ring Sum of Graphs
Abstract: A function f from vertex set V of a graph G to the set {0, 1, 2} is called 3-equitable labeling if the edge labels produced by absolute difference of the labels of end vertices of the respective edges in such a way that the number of edges with label i and j differ by atmost 1 and similarly the number of vertices with label i and j differby atmost …

Subtract Divisor Cordial Labeling of Ring Sum of a Graphs
Abstract: Abstract: A subtract divisor cordial labeling of a graph G with vertex set is a bijection f from V to {1, 2,…, |V|} such that an edge is assigned the label 1 if 2 divides (f(u) – f(v)) and 0 otherwise, then number of edges labeled with 0 and the number of edges labeled with 1 differ by at most 1. A graph with a subtract divisor cordial labeling is …

Vertex Odd Divisor Cordial Labeling of Ring Sum of Different Graphs With star Graph
Abstract: A graph tt = (V, E) is said to have a vertex odd divisor cordial labeling if there is a bijection f : {1, 3, . . . , 2n − 1} such that each edge e = uv is assigned the label 1 if f (u)|f (v) or f (v)|f (u) and 0 otherwise, then the number of edges labeled with 0 and the number of edges labeled with …
