Local antimagic chromatic number of partite graphs [PDF]

open access: yes, 2023
Let $G$ be a connected graph with $|V| = n$ and $|E| = m$. A bijection $f:E\rightarrow \{1,2,...,m\}$ is called a local antimagic labeling of $G$ if for any two adjacent vertices $u$ and $v$, $w(u) \neq w(v)$, where $w(u) = \sum_{e \in E(u)}f(e)$, and $E(

On Local Antimagic Chromatic Number of Cycle-Related Join Graphs [PDF]

open access: yes, 2021
An edge labeling of a connected graph G = (V, E) is said to be local antimagic if it is a bijection f : E → {1, . . ., |E|} such that for any pair of adjacent vertices x and y, f+(x) ≠ f+(y), where the induced vertex label f+(x) = Σf(e), with e ranging ...

On local edge antimagic chromatic number of graphs

open access: yes, 2022
Let G=(V,E) be a graph of order p and size q having no isolated vertices. A bijection f from V to {1,2,3,...,p} is called a local edge antimagic labeling if  for  any two adjacent edges e=uv and e'=vw of G, we have w(e) is not equal to w (e'), where the ...

open access: yes, 2022
Let G = (V,E) be a graph of order p and size q having no isolated vertices. A bijection ƒ : E → {1, 2, 3, ..., q} is called a local antimagic labeling if for all uv ∈ E we have w(u) ≠ w(v), the weight w(u) = ∑e∈E(u) f(e) where E(u) is the set of edges ...

An algorithmic approach in constructing infinitely many even size graphs with local antimagic chromatic number 3 [PDF]

open access: yes, 2023
An edge labeling of a connected graph $G = (V, E)$ is said to be local antimagic if it is a bijection $f:E \to\{1,\ldots ,|E|\}$ such that for any pair of adjacent vertices $x$ and $y$, $f^+(x)\not= f^+(y)$, where the induced vertex label $f^+(x)= \sum f(

open access: yes
An edge labeling of a connected graph G = (V, E) is said to be local antimagic if it is a bijection f: E → {1, …, |E|} such that for any pair of adjacent vertices x and y, f+ (x) ≠ f+ (y), where the induced vertex label f+ (x) =∑ f(e), with e ranging ...

On local antimagic total chromatic number of certain one point union of graphs [PDF]

open access: yes
Let $G = (V,E)$ be a connected simple graph of order $p$ and size $q$. A bijection $f:V(G)\cup E(G)\to \{1,2,\ldots,p+q\}$ is called a local antimagic total labeling of $G$ if for any two adjacent vertices $u$ and $v$, we have $w(u)\ne w(v)$, where $w(u)

The fractional chromatic number of triangle-free subcubic graphs [PDF]

open access: yes, 2014
Heckman and Thomas conjectured that the fractional chromatic number of any triangle-free subcubic graph is at most 14 / 5. Improving on estimates of Hatami and Zhu and of Lu and Peng, we prove that the fractional chromatic number of any triangle-free ...
