Suppose G=(V,E) is a graph with the vertex set V(G) and edge set E(G) we defined a labeling f:V?E?{1,2,…,k} to be an edge irregular total k-labeling of graph G if for every two different edge e and f there is wt(e)?wt(f). The minimum k for which the graph... see more

A G-supermagic labeling of a graph G=(V,E) is a bijection from E to a group G of order |E| such that the sum of labels of all edges incident with any vertex x? V is equal to the same element µ ? G. A Z2mn-supermagic labeling of the Cartesian product of tw... see more

Let G be a connected, simple, and undirrected graph, where V (G) is the vertex set and E(G) is the edge set. Let k be a natural numbers. For graph G we define a total k-labeling ? such that the vertices of graph G are labeled with {0, 2, 4, . . . , 2kv} a... see more

Several of the most studied graph labelings are injective functions, this constraint precludes some graphs from admitting such labelings; a well-known example is given by the family of trees that cannot be harmoniously labeled. In order to study the exist... see more

This study to present the result of research on the labeling, packaging and marketing strategies of sumpia products in addition to the importance of improving quality in term of content, it also needs special attention from various parties such as the gov... see more

Among the most studied graph labelings we have the varieties called alpha and edge-magic. Even when their definitions seem completely different, these labelings are related. A graceful labeling of a bipartite graph is called an a-labeling if the smaller l... see more

An ethical clearance document ensures that the research will protect the subject in accordance with existing ethical principles. The ethical clearance is issued by the Research Ethics Commission (KEP). KEP will conduct a review of the proposed ethical pro... see more

Let G(V,E) be a simple graph and f be a bijection f : V ? E ? {1, 2, …, |V|+|E|} where f(V)={1, 2, …, |V|}. For a vertex x ? V, define its weight w(x) as the sum of labels of all edges incident with x and the vertex label its... see more
