Bipartite biregular Moore graphs
Gabriela Araujo-Pardo, Cristina Dalfó, Miguel Ángel Fiol +1
A bipartite graph with is biregular if all the vertices of a stable set have the same degree for . In this paper, we give an improved n…
New results for the Mondrian art problem
C. Dalfó, M. A. Fiol, N. López
The Mondrian problem consists of dissecting a square of side length $n\in \NN$ into non-congruent rectangles with natural length sides such that the difference between the l…
On -Fibonacci digraphs
C. Dalfó, M. A. Fiol
The -Fibonacci digraphs , introduced here, have the number of vertices following generalized Fibonacci-like sequences. They can be defined both as digraphs on alphabets…
Spectra and eigenspaces from regular partitions of Cayley (di)graphs of permutation groups
C. Dalfó, M. A. Fiol
In this paper, we present a method to obtain regular (or equitable) partitions of Cayley (di)graphs (that is, graphs, digraphs, or mixed graphs) of permutation groups on letter…
On Cyclic Kautz Digraphs
Katerina Böhmová, Cristina Dalfó, Clemens Huemer
A prominent problem in Graph Theory is to find extremal graphs or digraphs with restrictions in their diameter, degree and number of vertices. Here we obtain a new family of digrap…
