Extension of α‐labelings of quadratic graphs
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 11, Page 571-578, 2004., 2004 First, a new proof for the existence of an α‐labeling of the quadratic graph Q(3, 4k) is presented. Then the existence of α‐labelings of special classes of quadratic graphs with some isomorphic components is shown.

Bounds of Strong EMT Strength for certain Subdivision of Star and Bistar
Open Mathematics, 2018 A super edge-magic total (SEMT) labeling of a graph ℘(V, E) is a one-one map ϒ from V(℘)∪E(℘) onto {1, 2,…,|V (℘)∪E(℘) |} such that ∃ a constant “a” satisfying ϒ(υ) + ϒ(υν) + ϒ(ν) = a, for each edge υν ∈E(℘), moreover all vertices must receive the ...

Applications of mathematical programming in graceful labeling of graphs
Journal of Applied Mathematics, Volume 2004, Issue 1, Page 1-8, 2004., 2004 Graceful labeling is one of the best known labeling methods of graphs. Despite the large number of papers published on the subject of graph labeling, there are few particular techniques to be used by researchers to gracefully label graphs. In this paper, first a new approach based on the mathematical programming technique is presented to model the ...

International Journal of Mathematics and Mathematical Sciences, Volume 29, Issue 8, Page 495-499, 2002., 2002 We construct a labeled graph D(n) that reflects the structure of divisors of a given natural number n. We define the concept of graceful numbers in terms of this associated graph and find the general form of such a number. As a consequence, we determine which graceful numbers are perfect.

Supermagic Generalized Double Graphs 1
Discussiones Mathematicae Graph Theory, 2016 A graph G is called supermagic if it admits a labelling of the edges by pairwise di erent consecutive integers such that the sum of the labels of the edges incident with a vertex is independent of the particular vertex.

Constant Sum Partition of Sets of Integers and Distance Magic Graphs
Discussiones Mathematicae Graph Theory, 2018 Let A = {1, 2, . . . , tm+tn}. We shall say that A has the (m, n, t)-balanced constant-sum-partition property ((m, n, t)-BCSP-property) if there exists a partition of A into 2t pairwise disjoint subsets A1, A2, . . . , At, B1, B2, . . .

Power domination in Mycielskian of spiders
AKCE International Journal of Graphs and Combinatorics, 2022 The power domination problem in graphs consists of finding a minimum set of vertices [Formula: see text] that monitors the entire graph G governed by two ‘monitoring rules’- domination and propagation. A set [Formula: see text] is a power dominating set (

All trees are six-cordial [PDF]
, 2017 For any integer $k>0$, a tree $T$ is $k$-cordial if there exists a labeling of the vertices of $T$ by $\mathbb{Z}_k$, inducing a labeling on the edges with edge-weights found by summing the labels on vertices incident to a given edge modulo $k$ so that ...

Open Mathematics, 2017 An edge-magic total labeling of an (n,m)-graph G = (V,E) is a one to one map λ from V(G) ∪ E(G) onto the integers {1,2,…,n + m} with the property that there exists an integer constant c such that λ(x) + λ(y) + λ(xy) = c for any xy ∈ E(G).
