On Generalized Token Graphs

Xiaodi Song, Cristina Dalfó, Miquel Àngel Fiol +2

The vertices of a $k$ -token graph of a graph $G$ correspond to $k$ indistinguishable tokens placed on $k$ different vertices of $G$ . Changing some conditions on both the nature of…

Metric representations by minimal graphs

Víctor Franco-Sánchez, Mercè Mora, María Luz Puertas

A resolving set in a graph $G$ is a vertex subset $W = {ω^{1}, \dots, ω^{n}} \subseteq V (G)$ such that each $u \in V (G)$ can be uniquely identified by the vector $r(u \vert W) = (d(u,…
