Group distance magic cubic graphs

Discussiones Mathematicae Graph Theory
A $\Gamma$\emph{-distance magic labeling} of a graph $G = (V, E)$ with $|V| = n$ is a bijection $\ell$ from $V$ to an Abelian group $\Gamma$ of order $n$, for which there exists $\mu \in \Gamma$, such that the weight $w(x) =\sum_{y\in N(x)}\ell(y)$ of ...

Group distance magic set of group vertex magic graphs

Journal of Combinatorial Mathematics and Combinatorial Computing
Let \(G\) be a graph of order \(n\) and let \(A\) be an additive Abelian group with identity 0. A mapping \(l : V(G) \to A \setminus \{0\}\) is said to be a \(A\)-vertex magic labeling of \(G\) if there exists a \(\mu \in\) \(A\) such that \(w(v) = \sum ...

On 14-regular distance magic graphs

Electronic Journal of Graph Theory and Applications
Let G be a graph with n vertices. By N ( v ) we denote the set of all vertices adjacent to v . A bijection f : V ( G ) → { 1 , 2 , . . . , n } is a distance magic labeling of G if there exists an integer k such that the sum of labels of all vertices ...

CHAPTER 3. ¹³C–¹³C Distance Measurements by Polarization Transfer Matrix Analysis of ¹³C Spin Diffusion in a Uniformly ¹³C-Labeled Molecular Complex under Magic Angle Spinning

2014
Spin diffusion of 13C polarization in NMR provides 13C−13C distances under magic angle spinning over a broad spectral width. However, there are difficulties in obtaining the distances accurately in uniformly 13C-labeled molecular complexes in solids. Effects of the weak long-range couplings are suppressed by strong short-range couplings.
