Antimagic labeling of a graph with vertices and edges is assigned the labels for its by some integers from set , such that no two received same label, weights are pairwise distinct. Where vertex-weights vertex under this sum all incident to vertex, in paper, we deal problem finding antimagic edge special families graphs called strong face graphs. We prove antimagic, ladder wheel fan prism final...
A graph G of order p and size q is called (a,d)-edge-antimagic total if there exists a one-to-one and onto mapping f from ∪ , ,... , such that the edge weights , ∈ form an AP progression with first term ’a’ and common difference ’d’. The graph G is said to be Super (a,d)-edge-antimagic total labeling if the , , ... , . In this paper we obtain Super (a,d)-edge-antimagic properties of certain cla...
Let G be a graph of order p and size q. An (a, d)-edge-antimagic total labeling of G is a one-to-one map f taking the vertices and edges onto 1, 2, . . . , p + q so that the edge-weights w(u, v) = f(u) + f(v) + f(uv), uv ∈ E(G), form an arithmetic progression, starting from a and having common difference d. Moreover, such a labeling is called super (a, d)edge-antimagic total if f(V (G)) = {1, 2...
An (a, d)-edge-antimagic total labeling of G is a one-to-one mapping g taking the vertices and edges onto 1, 2, . . . , |V (G)| + |E(G)| so that the edgeweights w(uv) = g(u) + g(v) + g(uv), uv ∈ E(G), form an arithmetic progression with initial term a and common difference d. Such a labeling is called super if the smallest labels appear on the vertices. In this paper, we investigate the existen...
An antimagic labeling of a finite undirected simple graph with m edges and n vertices is a bijection from the set of edges to the integers 1, . . . ,m such that all n vertex sums are pairwise distinct, where a vertex sum is the sum of labels of all edges incident with the same vertex. A graph is called antimagic if it has an antimagic labeling. In 1990, Hartsfield and Ringel [5] conjectured tha...
in this paper we construct antimagic labelings of the regular complete multipartite graphs and we also extend the construction to some families of regular graphs.
A graph $G$ is $k$-$weighted-list-antimagic$ if for any vertex weighting $\omega\colon V(G)\to\mathbb{R}$ and list assignment $L\colon E(G)\to2^{\mathbb{R}}$ with $|L(e)|\geq |E(G)|+k$ there exists an edge labeling $f$ such that $f(e)\in L(e)$ all $e\in E(G)$, labels of edges are pairwise distinct, the sum on incident to a plus weight distinct from at every other vertex. In this paper we prove ...
A graph G is k–weighted–list–antimagic if for any vertex weighting ω : V (G) → R and any list assignment L : E(G)→ 2R with |L(e)| ≥ |E(G)|+k there exists an edge labeling f such that f(e) ∈ L(e) for all e ∈ E(G), labels of edges are pairwise distinct, and the sum of the labels on edges incident to a vertex plus the weight of that vertex is distinct from the sum at every other vertex. In this pa...
