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.

Recent Submissions

  • Exponential stability in three-dimensional type III thermo-porous-elasticity with microtemperatures 

    Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-09-02)
    Article
    Restricted access - publisher's policy
    We study the time decay of the solutions for the type III thermoelastic theory with microtemperatures and voids. We prove that, under suitable conditions for the constitutive tensors, the solutions decay exponentially. ...
  • The neighborhood role in the linear threshold rank on social networks 

    Riquelme Csori, Fabián; Gonzalez Cantergiani, Pablo; Molinero Albareda, Xavier; Serna Iglesias, María José (2019-08-15)
    Article
    Restricted access - publisher's policy
    Centrality and influence spread are two of the most studied concepts in social network analysis. Several centrality measures, most of them, based on topological criteria, have been proposed and studied. In recent years new ...
  • On the exponential decay of solutions in dual-phase-lag porous thermoelasticity 

    Fernández, José Ramón; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (Springer, 2019-06-03)
    Part of book or chapter of book
    Restricted access - publisher's policy
    In the last years, a big interest has been developed to understand the time decay of solutions for the porous thermoelasticity with different thermal mechanisms. We here want to consider the problem of the one-dimensional ...
  • An axiomatization for two power indices for (3,2)-simple games 

    Benardi, Giulia; Freixas Bosch, Josep (2019-01-01)
    Article
    Restricted access - publisher's policy
    The aim of this work is to give a characterization of the Shapley–Shubik and the Banzhaf power indices for (3,2)-simple games. We generalize to the set of (3,2)-simple games the classical axioms for power indices on simple ...
  • Measuring satisfaction and power in influence based decision systems 

    Molinero Albareda, Xavier; Riquelme Csori, Fabián; Serna Iglesias, María José (2019-06-15)
    Article
    Restricted access - publisher's policy
    We introduce collective decision-making models associated with influence spread under the linear threshold model in social networks. We define the oblivious and the non-oblivious influence models. We also introduce the ...
  • On the uniqueness and analyticity in viscoelasticity with double porosity 

    Bazarra, Noelia; Fernández, José Ramón; Leseduarte Milán, María Carme; Magaña Nieto, Antonio; Quintanilla de Latorre, Ramón (2019-04-01)
    Article
    Open Access
    In this paper we analyze the system of equations that models the behaviour of materials with a double porous structure. We introduce dissipation mechanisms in both structures. We show existence, uniqueness and analyticity ...
  • Bounds for the Nakamura number 

    Freixas Bosch, Josep; Kurz, Sascha (Springer, 2019-04)
    Article
    Restricted access - publisher's policy
    The Nakamura number is an appropriate invariant of a simple game to study the existence of social equilibria and the possibility of cycles. For symmetric (quota) games its number can be obtained by an easy formula. For ...
  • The Owen and the Owen-Banzhaf values applied to the study of the Madrid Assembly and the Andalusian Parliament in legislature 2015-2019 

    Giménez Pradales, José Miguel; Puente del Campo, María Albina (Scitepress, 2019)
    Conference lecture
    Open Access
    This work focuses on the Owen value and the Owen-Banzhaf value, two classical concepts of solution defined on games with structure of coalition blocks. We provide a computation procedure for these solutions based on a ...
  • An equivalent formulation for the Shapley value 

    Freixas Bosch, Josep (Springer, 2018)
    Part of book or chapter of book
    Restricted access - publisher's policy
    These transactions publish research in computer-based methods of computational collective intelligence (CCI) and their applications in a wide range of fields such as the semantic web, social networks, and multi-agent ...
  • Qualitative results for a mixture of Green-Lindsay thermoelastic solids 

    Magaña Nieto, Antonio; Muñoz Rivera, Jaime E.; Naso, Maria Grazia; Quintanilla de Latorre, Ramón (2018-07)
    Article

    Article
    Restricted access - publisher's policy
    Voting games with abstention are voting systems in which players can cast not only yes and no vote, but are allowed to abstain. This paper centers on the structure of a class of complete games with abstention. We obtain, ...
