$Z_k$-Magic Labeling of Some Families of Graphs
Volume 50, issue 2 , December 2018, , Pages 1-12
Abstract
For any non-trivial abelian group A under addition a graph $G$ is said to be $A$-\textit{magic} if there exists a labeling $f:E(G) \rightarrow A-\{0\}$ such that, the vertex labeling $f^+$ defined as $f^+(v) = \sum f(uv)$ taken over all edges $uv$ incident at $v$ is a constant. An $A$-\textit{magic} ... Read MoreOne Modulo Three Geometric Mean Graphs
Volume 50, Issue 1 , June 2018, , Pages 101-108
Abstract
A graph $G$ is said to be one modulo three geometric mean graph if there is an injective function $\phi$ from the vertex set of $G$ to the set $\{a \mid 1\leq a \leq 3q-2\} $ and either $a\equiv 0(mod 3) $ or $ a\equiv 1(mod 3)\}$ where $q$ is the number of edges of $G$ and $\phi$ induces a bijection ...

Volume 50, Issue 1 , June 2018, , Pages 185-188
Abstract
A mapping $f: V(G)\rightarrow\left\{0, 1, 2 \right\}$ is called 3-product cordial labeling if $\vert v_f(i)-v_f(j)\vert \leq 1$ and $\vert e_f(i)-e_f(j)\vert \leq 1$ for any $ i, j\in \{0, 1, 2\}$, where $v_f(i)$ denotes the number of vertices labeled with $i, e_f (i)$ denotes the number ...

Volume 48, Issue 1 , December 2016, , Pages 57-68
Abstract
Let G be a (p,q) graph. An injective map f : E(G) → {±1,±2,...,±q} is said to be an edge pair sum labeling if the induced vertex function f*: V (G) → Z - {0} defi ned by f*(v) = ΣP∈Ev f (e) is one-one where Ev denotes the set of edges in G that are ... Read MoreTotal vertex irregularity strength of corona product of some graphs
Volume 48, Issue 1 , December 2016, , Pages 127-140
Abstract
A vertex irregular total k-labeling of a graph G with vertex set V and edge set E is an assignment of positive integer labels {1, 2, ..., k} to both vertices and edges so that the weights calculated at vertices are distinct. The total vertex irregularity strength of G, denoted by tvs(G)is the minimum ... Read MoreOn Generalized Weak Structures
Volume 47, Issue 1 , June 2016, , Pages 21-26
Abstract
Avila and Molina [1] introduced the notion of generalized weak structures which naturally generalize minimal structures, generalized topologies and weak structures and the structures α (g),π(g),σ(g) and β (g). This work is a further investigation of generalized weak structures due ... Read MoreTotally magic cordial labeling of some graphs
Volume 46, Issue 1 , December 2015, , Pages 1-8
Abstract
A graph G is said to have a totally magic cordial labeling with constant C if there exists a mapping f : V (G) ∪ E(G) → {0, 1} such that f(a) + f(b) + f(ab) ≡ C (mod 2) for all ab ∈ E(G) and |nf (0) − nf (1)| ≤ 1, where nf (i) (i = 0, 1) is the sum of ...

Volume 46, Issue 1 , December 2015, , Pages 27-34
Abstract
Let G be a graph with p vertices and q edges and A = {0, 1, 2, . . . , [q/2]}. A vertex labeling f : V (G) → A induces an edge labeling f∗ defined by f∗(uv) = f(u) + f(v) for all edges uv. For a ∈ A, let vf (a) be the number of vertices v with f(v) = a. A ... Read MoreSkolem Odd Difference Mean Graphs
Volume 45, Issue 1 , December 2014, , Pages 1-12
Abstract
In this paper we define a new labeling called skolem odd difference mean labeling and investigate skolem odd difference meanness of some standard graphs. 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, ... Read MoreEdge pair sum labeling of spider graph
Volume 45, Issue 1 , December 2014, , Pages 25-34
Abstract
An 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 ...
