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…
New results on the degree/diameter problem of mixed Abelian Cayley graphs
C. Dalfó, M. A. Fiol, N. López
Mixed graphs can be seen as digraphs that have both arcs and edges (or digons, that is, two opposite arcs). In this paper, we consider the case in which such graphs are Cayley grap…
On bipartite mixed graphs
C. Dalfó, M. A. Fiol, N. López
Mixed graphs can be seen as digraphs that have both arcs and edges (or digons, that is, two opposite arcs). In this paper, we consider the case where such graphs are bipartite. As…
An improved Moore bound for mixed graphs
C. Dalfó, M. A. Fiol, N. López
A mixed graph can contain both (undirected) edges and arcs (directed edges). Here we derive an improved Moore-like bound for the maximum number of vertices of a mixed graph wit…
Sequence mixed graphs
C. Dalfó, M. A. Fiol, N. López
A mixed graph can be seen as a type of digraph containing some edges (two opposite arcs). Here we introduce the concept of sequence mixed graphs, which is a generalization of both…
