  • Coalition formation and stability 

    Magaña Nieto, Antonio; Carreras Escobar, Francisco (2018-06)
    Article
    Accés restringit per política de l'editorial
    This paper aims to develop, for any cooperative game, a solution notion that enjoys stability and consists of a coalition structure and an associated payoff vector derived from the Shapley value. To this end, two concepts ...
  • The Shapley value analyzed under the Felsenthal and Machover bargaining model 

    Bernardi, Giulia; Freixas Bosch, Josep (2018-05-23)
    Article
    Accés restringit per política de l'editorial
    In 1996, Felsenthal and Machover proposed a bargaining procedure for a valuable payoff in cooperative and simple games. They proved that the value underlying their bargaining scheme was the Shapley value by showing that ...
  • Bisemivalues for bicooperative games 

    Domènech Blázquez, Margarita; Giménez Pradales, José Miguel; Puente del Campo, María Albina (2018-02-04)
    Article
    Accés restringit per política de l'editorial
    We introduce bisemivalues for bicooperative games and we also provide an interesting characterization of this kind of values by means of weighting coefficients in a similar way as it was given for semivalues in the context ...
  • 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. ...
  • A note on multinomial probabilistic values 

    Carreras Escobar, Francisco; Puente del Campo, María Albina (Springer, 2018-04)
    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 ...
  • 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 obert
    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 ...
  • Weighted voting, abstention and multiple levels of approval 

    Freixas Bosch, Josep; Zwicker, William S. (Springer, 2003-12)
    Article
    Accés obert
    In this paper we introduce the class of simple games with several ordered levels of approval in the input and in the output – the ( j,k) simple games – and propose a definition for weighted games in this context. Abstention ...
  • Effect of a science communication event on students’ attitudes towards science and technology 

    Torras Melenchón, Núria; Grau Vilalta, Maria Dolors; Font Soldevila, Josep; Freixas Bosch, Josep (Tempus Publications, 2017)
    Article
