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.

Cellular properties of nilpotent spaces
(Mathematical Sciences Publishers, 2015-10)We show that cellular approximations of nilpotent Postnikov stages are always nilpotent Postnikov stages, in particular ...

Cryptography with right-angled Artin groups
(Polish Academy of Sciences, 2016)In this paper we propose right-angled Artin groups as a platform for secret sharingschemes based on the efficiency (linear ...

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 ...

Generators and closed classes of groups
(Universitat Autònoma de Barcelona, Departament de Matemàtiques, 2021)We show that, in the category of groups, every singly-generated class which is closed under isomorphisms, direct limits, ...

Homogeneity test for functional data
(Taylor & Francis, 2017)In the context of functional data analysis, we propose new two sample tests for homogeneity. Based on some well-known depth ...

Homotopy idempotent functors on classifying spaces
(American Mathematical Society, 2015-02)Fix a prime p. Since their definition in the context of Localization Theory, the homotopy functors PBZ/p and CWBZ/p have ...

K-homology and K-theory for the lamplighter groups of finite groups
(London Mathematical Society, 2017-08)Let F be a finite group. We consider the lamplighter group L = F ≀ Z over F. We prove that L has a classifying space for ...

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 ...

Nullification functors and the homotopy type of the classifying space for proper bundles
(Mathematical Sciences Publishers, 2005-09)Let G be a discrete group for which the classifying space for proper G-actions is finite-dimensional. We find a space W ...

On localizations of quasi-simple groups with given countable center
(EMS Press, 2020-10-22)A group homomorphism � : � → � i:H→G is a localization of � H, if for every homomorphism � : � → � φ:H→G ...

On the classifying space for proper actions of groups with cyclic torsion
(De Gruyter, 2014-01)In this paper we introduce a common framework for describing the topological part of the Baum-Connes conjecture for a ...

On the idempotency of some composite functors
(Springer, 2012-01)We present examples of localization functors whose composition with certain cellularization functors is not idempotent, and vice versa.

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 ...

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.
