Perfect super edge - magic graphs
In this paper we introduce the concept of perfect super edge-magic graphs and we prove some classes of graphs to be perfect super edge-magic.
متن کاملSuper Edge-Magic Models
In this paper, we generalize the concept of super edge-magic graph by introducing the new concept of super edge-magic models.
متن کاملOn super edge-magic graphs which are weak magic
A (p,q) graph G is total edge-magic if there exits a bijection f: Vu E ~ {1.2,. .. ,p+q} such that for each e=(u,v) in E, we have feu) + fee) + f(v) as a constant. For a graph G, denote M(G) the set of all total edge-magic labelings. The magic strength of G is the minimum of all constants among all labelings in M(G), and denoted by emt(G). The maximum of all constants among M(G) is called the m...
متن کاملEnlarging the classes of super edge-magic 2-regular graphs
A graph G is called super edge-magic if there exists a bijective function f : V (G) ∪ E (G) → {1, 2, . . . , |V (G)|+ |E (G)|} such that f (V (G)) = {1, 2, . . . , |V (G)|} and f (u) + f (v) + f (uv) is a constant for each uv ∈ E (G). A graph G with isolated vertices is called pseudo super edge-magic if there exists a bijective function f : V (G) → {1, 2, . . . , |V (G)|} such that the set {f (...
متن کاملOn super edge-magic total labeling on subdivision of trees
An edge-magic total labeling of a graph G is a one-toone map λ from V (G) ∪ E(G) onto the integers {1, 2, · · · , |V (G) ∪ E(G)|} with the property that, there is an integer constant c such that λ(x) + λ(x, y) + λ(y) = c for any (x, y) ∈ E(G). If λ(V (G)) = {1, 2, · · · , |V (G|} then edge-magic total labeling is called super edgemagic total labeling. In this paper we formulate super edge-magic...
