On the Spectra of Generalized Token Graphs of Stars

Cristina Dalfó, Miquel Àngel Fiol, Berenice Martínez-Barona +1

In the generalization of token graphs (or supertoken graphs), the vertices of a $k$ -token graph of a graph $G$ correspond to $k$ distinguishable or indistinguishable tokens placed…

The Algebraic Connectivity and Laplacian Spectral Radius of Token Graphs

Xiaodi Song, Cristina Dalfó, Miquel Àngel Fiol +1

For a graph $G = (V, E)$ of order $n$ and an integer $k$ between $1$ and $⌊ \frac{n}{2} ⌋$ , its token graph $F_{k} (G)$ is the graph whose vertices consist of the $\binom{n}{k}…
