El grup té una experiència de més de vint anys en el seu camp d’expertesa, la teoria de jocs i les seves aplicacions. El grup ha mantingut una línia creixent tant pel que fa a la producció científica contrastada com pel coneixement en l’àmbit. El grup és avui un referent internacional en àrees específiques com ara els sistemes de votació i els jocs cooperatius així com en les seves aplicacions: tecnològiques, econòmiques, polítiques i sociològiques.
Els seus treballs són matemàticament rigorosos i concisos, i els seus membres són bons coneixedors de l’àlgebra, la matemàtica discreta, la probabilitat, la complexitat o la computació. Nombroses situacions extretes de la vida quotidiana els han estimulat a modelitzar, simular i proposar propostes de solució o de millora.
Els seus membres comparteixen nombroses publicacions de prestigi, vetllen per la creixent internacionalització del grup, tenen cura de la formació i divulguen els seus treballs.

Research in the foundations and applications of game theory. The main theoretical lines are the following: (a) cooperative games and solution concepts; (b) collective decision-making mechanisms and power indices; (c) restrictions to cooperation; (d) multiplicity of alternatives; and (e) software. The areas of application include economics, political science, sociology, management, industrial scheduling and technologies such as cryptography and reliability.

  • Semivalues: weighting coefficients and allocations on unanimity games 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2017-12-12)
    Article
    Accés restringit per política de l'editorial
    Each semivalue, as a solution concept defined on cooperative games with a finite set of players, is univocally determined by weighting coefficients that apply to players’ marginal contributions. Taking into account that a ...
  • On the existence and uniqueness in phase-lag thermoelasticity 

    Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2018-01)
    Article
    Accés restringit per política de l'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. ...
  • Preorders in simple games 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer, 2017)
    Capítol de llibre
    Accés restringit per política de l'editorial
    Any power index defines a total preorder in a simple game and, thus, induces a hierarchy among its players. The desirability relation, which is also a preorder, induces the same hierarchy as the Banzhaf and the Shapley ...
  • A note on multinomial probabilistic values 

    Carreras Escobar, Francisco; Puente del Campo, María Albina (Springer, 2017-12)
    Article
    Accés restringit per política de l'editorial
    Multinomial values were previously introduced by one of the authors in reliability and extended later to all cooperative games. Here, we present for this subfamily of probabilistic values three new results, previously ...
  • Centrality measure in social networks based on linear threshold model 

    Riquelme Csori, Fabián; Gonzalez Cantergiani, Pablo; Molinero Albareda, Xavier; Serna Iglesias, María José (2018-01-15)
    Article
    Accés restringit per política de l'editorial
    Centrality and influence spread are two of the most studied concepts in social network analysis. In recent years, centrality measures have attracted the attention of many researchers, generating a large and varied number ...
  • On the viscoelastic mixtures of solids 

    Fernández, Jose R.; Magaña Nieto, Antonio; Masid, Maria; Quintanilla de Latorre, Ramón (2017-07-12)
    Article
    Accés restringit per política de l'editorial
    In this paper we analyze an homogeneous and isotropic mixture of viscoelastic solids. We propose conditions to guarantee the coercivity of the internal energy and also of the dissipation, first in dimension two and later ...
  • Combinatorial structures to modeling simple games and applications 

    Molinero Albareda, Xavier (American Institute of Physics (AIP), 2017)
    Text en actes de congrés
    Accés obert
    We connect three different topics: combinatorial structures, game theory and chemistry. In particular, we establish the bases to represent some simple games, defined as influence games, and molecules, defined from atoms, ...
  • On the characterization of weighted simple games 

    Freixas Bosch, Josep; Freixas Boleda, Marc; Kurz, Sascha (2017-12)
    Capítol de llibre
    Accés restringit per política de l'editorial
    This paper has a twofold scope. The first one is to clarify and put in evidence the isomorphic character of two theories developed in quite different fields: on one side, threshold logic, on the other side, simple games. ...
  • 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 ...
  • Using the multilinear extension to study some probabilistic power indices 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (2017-05-01)
    Article
    Accés restringit per política de l'editorial
    We consider binary voting systems modeled by a simple game, in which voters vote independently of each other, and the probability distribution over coalitions is known. The Owen’s multilinear extension of the simple game ...
  • On alpha-roughly weighted games 

    Freixas Bosch, Josep; Kurz, Sascha (2011-12-13)
    Report de recerca
    Accés obert
    Very recently Gvozdeva, Hemaspaandra, and Slinko (2011) h ave introduced three hierarchies for simple games in order to measure the distance of a given simple game to the class of weighted voting games or roughly weighted ...
  • The complexity of testing properties of simple games 

    Freixas Bosch, Josep; Molinero Albareda, Xavier; Olsen, Martin; Serna Iglesias, María José (2008-04-04)
    Report de recerca
    Accés obert
    Simple games cover voting systems in which a single alternative, such as a bill or an amendment, is pitted against the status quo. A simple game or a yes-no voting system is a set of rules that specifies exactly which ...
