Let G = (V,E) be a graph with p vertices and q edges. G is said be skolem odd difference mean if there exists a function f : V (G) → {0, 1, 2, 3, . . . , p + 3q − 3} satisfying f is 1−1 and the induced map f : E(G) → {1, 3, 5, . . . , 2q−1} denoted by f*(e) =|f(u)−f(v)|/2 is a bijection. A graph that admits skolem odd difference mean labeling is called odd difference mean graph. We call skolem odd difference mean labeling as skolem even vertex odd difference mean labeling if all the vertex labels are even.https://jac.ut.ac.ir/article_7916_727d297ed723f77921f5f0cb0b62cd65.pdfUniversity of TehranJournal of Algorithms and Computation2476-277645120141115Three Graceful Operations13247917ENSarahMinionDepartment of Mathematics, Clayton State University, Morrow, Georgia 30260, USAChristianBarrientosDepartment of Mathematics, Clayton State University, Morrow, Georgia 30260, USAJournal Article20140726A graph of size n is said to be graceful when is possible toassign distinct integers from {0, 1, . . . , n} to its verticesand {|f(u)−f(v)| : uv ∈ E(G)} consists of n integers. Inthis paper we present broader families of graceful graphs; these families are obtained via three different operations: the third power of a caterpillar, the symmetric product of G and K2 , and the disjoint union of G and Pm, where G is a special type of graceful graph named - graph. Moreover, the majority of the graceful labelings obtained here correspond to the most restrictive kind, they are -labelings. These labelings are in the core of this research area due to the fact that they can be used to create other types of graph labelings, almost independently of the nature of these labelings.https://jac.ut.ac.ir/article_7917_40bafdc72fac86dcf4daf6687498fa6f.pdfUniversity of TehranJournal of Algorithms and Computation2476-277645120141120Edge pair sum labeling of spider graph25347918ENP.JeyanthiResearch Centre, Department of Mathematics, Govindammal Aditanar College for Women Tiruchendur, Tamil Nadu, India.T.Saratha DeviDepartment of Mathematics, G. Venkataswamy Naidu College, Kovilpatti, Tamil Nadu, India.Journal Article20140520An injective map f : E(G) → {±1, ±2, · · · , ±q} is said to be an edge pair sum labeling of a graph G(p, q) if the induced vertex function f*: V (G) → Z − {0} defined by f*(v) = (Sigma e∈Ev) f (e) is one-one, where Ev denotes the set of edges in G that are incident with a vetex v and f*(V (G)) is either of the form {±k1, ±k2, · · · , ±kp/2} or {±k1, ±k2, · · · , ±k(p−1)/2} U {k(p+1)/2} according as p is even
or odd. A graph which admits edge pair sum labeling is called an edge pair sum graph.
