    • Application of Cauchy's equation in combinatorics and genetics 

      Kannappan, Palaniappan (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2001)
      Article
      Accés obert
      We are familiar with the combinatorial formula $\left(\begin{array}{cc} n\\ r \end{array}\right) = \frac{n(n-1) \cdots (n - r + 1)}{r !} = $ number of possible ways of choosing $r$ objects out of $n$ objects\,. In ...

    • Asymptotic behaviour of the domain of analyticity of invariant curves of the standard map 

      Martínez-Seara Alonso, M. Teresa; Villanueva Castelltort, Jordi (1999)
      Article
      Accés obert
      In this paper we consider the standard map, and we study the invariant curve obtained by analytical continuation, with respect to the perturbative parameter E, of the invariant circle of rotation number the golden mean ...

    • Combining degrees of impairment: the case of the index of Balthazard 

      Alsina Català, Claudi; Trillas i Gay, Enric; Moraga, Claudio (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2003)
      Article
      Accés obert
      Using techniques for modeling indices by means of functional equations and resources from fuzzy set theory, the classical Balthazard index used in order to combine several degrees of impairment is characterized in two ...

    • Gramáticas discriminantes y funciones discriminantes lineales generalizadas 

      García Fornes, Ana; Ruiz Calomarde, Antonio; Vidal Ruiz, Enrique; Cascuberta Nolla, Francisco (Universitat Politècnica de Catalunya. Centre de Càlcul, 1989)
      Article
      Accés obert
      Las Gramáticas Discriminantes constituyen una aproximación para la clasificación de frases generadas por Gramáticas cuando la presencia de ruidos y distorsiones hace difícil la aplicación de las Técnicas usuales de Análisis ...

    • On inner product spaces-II 

      Kannappan, Palaniappan (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
      Article
      Accés obert
      Among normal linear spaces, the inner product spaces (i.p.s.) are particularly interesting. Many characterizations of i.p.s. among linear spaces are known using various functional equations. Three functional equations ...

    • Three-dimensional quasiperiodic torsional flows in rotating spherical fluids at very low Prandtl numbers 

      Sánchez Umbría, Juan; Net Marcé, Marta (2021-11-04)
      Article
      Accés obert
      The aim of this study is to determine through numerical simulations the extent and robustness of the three-dimensional torsional dynamics of the thermal convection in rotating spherical fluids at very low Prandtl numbers. ...
