Constant Sum Partition of ${1, 2, ..., n}$ Into Subsets With Prescribed Orders

V. Vilfred Kamalappan, Sajidha P

Studies on partition of $I_{n}$ = ${1, 2, ..., n}$ into subsets $S_{1}, S_{2}, ..., S_{x}$ so far considered with prescribed sum of the elements in each subset. In this paper, we s…

Cylindrical Grid Graphs $P_{m} □ C_{n}$ are Non-Distance Magic

Sajidha P, V. Vilfred Kamalappan, Julia K. Abraham

A bijective mapping $f : V (G) \to {1, 2, \dots, n}$ is called a \emph{Distance Magic Labeling (DML) of $G$ } if ~ $\sum_{v \in N (u)} f (v)$ is a constant for all…

Finding Non-Distance Magic Graphs using neighbourhood chains

V. Vilfred Kamalappan, Sajidha P

Let $G$ be a graph of order $n$ and $N = {N (u_{i})}_{i = 1}^{k}$ be a sequence of neighbourhood(nbh)s in $G$ where $N (u)$ = ${v \in V (G) :$ $uv \in E (G)}$ . \emph{Nbh sequence graph $H…
