A note on three-quarters circulant digraphs
C. Dalfó, M. A. Fiol, M. A. Reyes
We introduce and study a new family of circulant digraphs associated with the cyclic group , obtained by restricting admissible combinations of two generators and to…
On the achromatic index of Johnson graphs
Gabriela Araujo-Pardo, Cristina Dalfó, Mónica Reyes
In this paper, we study proper and complete edge-colorings of Johnson graphs , also called -triangular graphs. They are isomorphic both to the 2-token graphs of complete…
On supertoken graphs
Mónica A. Reyes, Cristina Dalfó, Miquel Àngel Fiol
We generalize the concept of token graphs to obtain supertoken graphs. In the latter case, there can be more than one token in a vertex. We formally define supertoken graphs and es…
On Generalized Token Graphs
Xiaodi Song, Cristina Dalfó, Miquel Àngel Fiol +2
The vertices of a -token graph of a graph correspond to indistinguishable tokens placed on different vertices of . Changing some conditions on both the nature of…
On the spectra and spectral radii of token graphs
M. A. Reyes, C. Dalfó, M. A. Fiol
Let be a graph on vertices. The -token graph (or symmetric -th power) of , denoted by has as vertices the -subsets of vertices from ,…
