  • Coalition formation and stability 

    Magaña Nieto, Antonio; Carreras Escobar, Francisco (2018-06)
    Article
    Open Access
    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 ...
