The cellular structure of the classifying spaces of finite groups
(Springer, 2011-08)
In this paper we obtain a description of the BZ/p-cellularization (in the sense of Dror-Farjoun) of the classifying spaces of all finite groups, for all primes p.

Cellular covers of local groups
(Springer, 2018-12)
We prove that, in the category of groups, the composition of a cellularization and a localization functor need not be idempotent. This provides a negative answer to a question of Emmanuel Dror Farjoun.

Nullification and cellularization of classifying spaces of finite groups
(American Mathematical Society, 2007-04)
In this note we discuss the effect of the BZ/p-nullification PBZ/p and the BZ/p-cellularization CWBZ/p over classifying spaces of finite groups, and we relate them with the corresponding functors with respect to Moore ...

Polynomial braid combing
(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.

Pyramidal values
(Springer, 2014-06)
We propose and analyze a new type of values for cooperative TU-games, which we call pyramidal values. Assuming that the grand coalition is sequentially formed, and all orderings are equally likely, we define a pyramidal ...

Expanders and right-angled Artin groups
(World Scientific Publishing Company, 2021)
The purpose of this paper is to give a characterization of families of expander graphs via right-angled Artin groups. We prove that a sequence of simplicial graphs {Γi}i∈N forms a family of expander graphs if and only ...
