  • Online matching in regular bipartite graphs 

    Barrière Figueroa, Eulalia; Fuchs, Janosch; Muñoz Lopez, Xavier; Unger, Walter (2018-06-01)
    Article
    Open Access
    In an online problem, the input is revealed one piece at a time. In every time step, the online algorithm has to produce a part of the output, based on the partial knowledge of the input. Such decisions are irrevocable, ...
  • On the Hierarchical Product of Graphs and the Generalized Binomial Tree 

    Barrière Figueroa, Eulalia; Comellas Padró, Francesc de Paula; Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel (2007-09)
    Article
    Open Access
    In this paper we follow the study of the hierarchical product of graphs, an operation recently introduced in the context of networks. A well-known example of such a product is the binomial tree which is the (hierarchical) ...
  • On the spectra of hypertrees 

    Barrière Figueroa, Eulalia; Comellas Padró, Francesc de Paula; Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel (2007-05)
    Article
    Open Access
    In this paper we study the spectral properties of a family of trees characterized by two main features: they are spanning subgraphs of the hypercube, and their vertices bear a high degree of (connectedness) hierarchy. ...
  • Sediment 

    Barrière Figueroa, Eulalia; Fages, Ferran (2018)
    Conference report
    Restricted access - publisher's policy
    Sediment is a series of abstract narrations which combine the generative visuals of Lali Barrière with the static music of Ferran Fages, with a clearly minimalist approach. The visuals use a single graphic element: the ...
  • Teaching mathematics and physics for animation in processing 

    Barrière Figueroa, Eulalia (Tessellations Publishing, 2018)
    Conference report
    Restricted access - publisher's policy
    This paper describes my teaching experience with first year undergraduate students, at the Centre de la Imatge i la Tecnologia Multimèdia (CITM), in Terrassa, a city near Barcelona (Catalonia) during the Fall 2017 semester. ...
  • The Frobenius problem: a geometric approach 

    Barrière Figueroa, Eulalia; Miralles de la Asunción, Alicia (2007-07)
    Article
    Open Access
    For the well known Frobenius problem, we present a new geometric approach, based on the use of the $n$-dimensional lattice $\mathbb{Z}^n$, where $n$ is the number of generators. Within this approach we are able to study ...
  • The generalized hierarchical product of graphs 

    Barrière Figueroa, Eulalia; Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel; Mitjana Riera, Margarida (2008-01)
    Article
    Open Access
    A generalization of both the hierarchical product and the Cartesian product of graphs is introduced and some of its properties are studied. We call it the generalized hierarchical product. In fact, the obtained graphs ...
  • The hierarchical product of graphs 

    Barrière Figueroa, Eulalia; Comellas Padró, Francesc de Paula; Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel (2007)
    Article
    Open Access
    A new operation on graphs is introduced and some of its properties are studied. We call it hierarchical product, because of the strong (connectedness) hierarchy of the vertices in the resulting graphs. In fact, the ...
