On the Automorphisms of Token Graphs Generated by $2$ -cuts with the Same Neighbours

Ruy Fabila-Monroy, Sergio Gerardo Gómez-Galicia, Daniel Gregorio-Longino +2

Let $G$ be a connected graph on $n$ vertices and $1 \leq k \leq n - 1$ an integer. The $k$ -token graph of $G$ is the graph $F_{k} (G)$ whose vertices are all the $k$ -subsets of vertices o…

A Note on the Asymptotic Value of the Isoperimetric Number of $J (n, 2)$

Ruy Fabila-Monroy, Daniel Gregorio-Longino

Let $G$ be a graph on $n$ vertices and $S$ a subset of vertices of $G$ ; the boundary of $S$ is the set, $\partial S$ , of edges of $G$ connecting $S$ to its complement in $G$ . The…
