Domination, matching and transversal numbers for Berge- hypergraphs
María José Chávez de Diego, Pablo Montero Moreno, María Trinidad Villar-Liñán
Let be a graph and be a hypergraph. The hypergraph is a {\it Berge-G} if there is a bijection such that for each $e \in…
Note on power hypergraphs with equal domination and matching numbers
María José Chávez de Diego, Pablo Montero Moreno, María Trinidad Villar-Liñán
We present some examples that refute two recent results in the literature concerning the equality of the domination and matching numbers for power and generalized power hypergraphs…
Connecting Statistics, Probability, Algebra and Discrete Mathematics
Fernando López-Blázquez, Juan Núñez-Valdés, Silvia Recacha +1
In this paper, we connect four different branches of Mathematics: Statistics, Probability, Algebra and Discrete Mathematics with the objective of introducing new results on Markov…
Gradation in Greyscales of Graphs
Natalia de Castro, María A. Garrido-Vizuete, Rafael Robles +1
In this work we present the notion of greyscale of a graph as a colouring of its vertices that uses colours from the real interval [0,1]. Any greyscale induces another colouring by…
