    Polynomial braid combing 

    Flores Díaz, Ramón Jesús; González-Meneses López, Juan (Oxford University Press, 2018)
    We prove that, for n ≥ 3, the minimal dimension of a model of the classifying space of the braid group Bn, and of the pure braid group Pn, with respect to the family of virtually cyclic groups is n.
