  • Instability and bifurcation in a trend depending price formation model 

    González Nogueras, María del Mar; Gualdani, Maria Pia; Solà-Morales Rubió, Joan de (2016-08)
    Artículo

    A well-known model due to J.-M. Lasry and P.L. Lions that presents the evolution of prices in a market as the evolution of a free boundary in a diffusion equation is modified in order to show instabilities for some values ...
  • Convergence to steady-state and boundary layer profiles in a linear chromatography system 

    Menacho, Joaquín; Solà-Morales Rubió, Joan de (2015-01-01)
    Artículo

    We study the hyperbolic system of equations of the so-called linear transport model in a true moving bed chromatography device with four ports. By using methods based on a suitable energy functional we show that all solutions ...
  • Implementing data-dependent triangulations with higher order delaunay triangulations

    The Delaunay triangulation is the standard choice for building triangulated irregular networks (TINs) to represent terrain surfaces. However, the Delaunay triangulation is based only on the 2D coordinates of the data points, ...
  • Qualitative properties in strain gradient thermoelasticity with microtemperatures 

    Iesan, Dorin; Quintanilla de Latorre, Ramón (2018-02-01)
    Artículo
    Acceso abierto
    This paper is devoted to the strain gradient theory of thermoelastic aterials whose microelements possess microtemperatures. The work is motivated by an increasing use of materials which possess thermal variation at a ...
  • On the existence and uniqueness in phase-lag thermoelasticity 

    Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2018-01)
    Artículo
    Acceso restringido por política de la editorial
    This paper is devoted to analyze the phaselag thermoelasticity problem. We study two different cases and we prove, for each one of them, that the solutions of the problem are determined by a quasicontractive semigroup. ...
  • On the Sato-Tate conjecture for non-generic abelian surfaces 

    Johansson, Christian; Fite Naya, Francesc (2017-01)
    Artículo
    Acceso abierto
    We prove many non-generic cases of the Sato-Tate conjecture for abelian surfaces as formulated by Fité, Kedlaya, Rotger and Sutherland, using the potential automorphy theorems of Barnet-Lamb, Gee, Geraghty and Taylor.
  • Seducir matematicamente?

  • GPS differential code biases determination: methodology and analysis 

    Sanz Subirana, Jaume; Juan Zornoza, José Miguel; Rovira Garcia, Adrià; González Casado, Guillermo (2017-10)
    Artículo
    Acceso restringido por política de la editorial
    We address two main problems related to the receiver and satellite differential code biases (DCBs) determination. The first issue concerns the drifts and jumps experienced by the DCB determinations of the International ...
  • Eccentricity samples: implications on the potential and the velocity distribution 

    Cubarsí Morera, Rafael; Stojanovic, Milan; Ninkovic, Slobodan (2017)
    Artículo
    Acceso abierto
    Planar and vertical epicycle frequencies and local angular velocity are related to the derivatives up to the second order of the local potential and can be used to test the shape of the potential from stellar disc samples. ...
  • Revisiting Kneser’s theorem for field extensions 

    Bachoc, Christine; Serra Albó, Oriol; Zemor, Gilles (2017-05-31)
    Artículo

    A Theorem of Hou, Leung and Xiang generalised Kneser’s addition Theorem to field extensions. This theorem was known to be valid only in separable extensions, and it was a conjecture of Hou that it should be valid for all ...
