Item New Methods for Magic Total Labelings of Graphs(2015-05) Singgih, InneA \textit{vertex magic total (VMT) labeling} of a graph $G=(V,E)$ is a bijection from the set of vertices and edges to the set of numbers defined by $\lambda:V\cup E\rightarrow\{1,2,\dots,|V|+|E|\}$ so that for every $x \in V$ and some integer $k$, $w(x)=\lambda(x)+\sum_{y:xy\in E}\lambda(xy)=k$. An \textit{edge magic total (EMT) labeling} is a bijection from the set of vertices and edges to the set of numbers defined by $\lambda:V\cup E\rightarrow\{1,2,\dots,|V|+|E|\}$ so that for every $xy \in E$ and some integer $k$, $w(xy)=\lambda(x)+\lambda(y)+\lambda(xy)=k$. Numerous results on labelings of many families of graphs have been published. In this thesis, we include methods that expand known VMT/EMT labelings into VMT/EMT labelings of some new families of graphs, such as unions of cycles, unions of paths, cycles with chords, tadpole graphs, braid graphs, triangular belts, wheels, fans, friendships, and more.
