    • Semivalues: power, potential and multilinear extensions 

      Carreras Escobar, Francisco; Giménez Pradales, José Miguel (2009-04)
      Report de recerca
      Accés obert
      The notions of power and potential, both defined for any semivalue, give rise to two endomorphisms of the vector space of all cooperative games on a given player set. Several properties of these linear mappings are stated ...

    • Separability by semivalues modified for games with coalition structure 

      Amer Ramon, Rafael; Giménez Pradales, José Miguel (2009-06)
      Article
      Accés obert
      Two games are inseparable by semivalues if both games obtain the same allocation whatever semivalue is considered. The problem of separability by semivalues reduces to separability from the null game. For four or more ...

    • Si és convexa ha de ser simple 

      Mas Colell, Andreu (2017-05-03)
      Audiovisual
      Accés obert
      En el context de la teoria dels jocs d’estratègia descriuré un ben conegut concepte de solució anomenat “equilibri correlacionat” (una generalització molt natural de l'equilibri de Nash). A continuació explicaré com els ...

    • Similarities and differences between success and decisiveness 

      Freixas Bosch, Josep; Pons Vallès, Montserrat (AA Publications, 2014)
      Text en actes de congrés
      Accés obert
      We consider binary voting systems in which a probability distribution over coalitions is known. In this broader context decisiveness is an extension of the Penrose-Banzhaf index and success an extension of the Rae index ...

    • Simple games and weighted games: a theoretical and computational viewpoint

      Article
      Accés obert
      We analyze assortative assignment games, introduced in Becker (1973) and Eriksson et al. (2000). We study the extreme core points and show an easy way to compute them. We find a natural solution for these games. It coincides ...

      Freixas Bosch, Josep; Molinero Albareda, Xavier (2006-01)
      Report de recerca
      Accés obert
      In voting systems, game theory, switching functions, threshold logic, hypergraphs or coherent structures there is an important problem that consists in determining the weightedness of a voting system by means of trades ...
