On the Laplacian spectra of token graphs
C. Dalfó, F. Duque, R. Fabila-Monroy +4
We study the Laplacian spectrum of token graphs, also called symmetric powers of graphs. The -token graph of a graph is the graph whose vertices are the -subsets…

Decompositions of a rectangle into non-congruent rectangles of equal area
C. Dalfó, M. A. Fiol, N. López +1
In this paper, we deal with a simple geometric problem: Is it possible to partition a rectangle into non-congruent rectangles of equal area? This problem is motivated by the so…

An improved Moore bound and some new optimal families of mixed Abelian Cayley graphs
C. Dalfó, M. A. Fiol, N. López +1
We consider the case in which mixed graphs (with both directed and undirected edges) are Cayley graphs of Abelian groups. In this case, some Moore bounds were derived for the maxim…
