Esferas de homología

Flores Díaz, Ramón Jesús; Delgado Tejada, Juan Antonio (2020-01-01)

Torsion homology and cellular approximation

Flores Díaz, Ramón Jesús; Muro Jiménez, Fernando (Mathematical Sciences Publishers, 2019-02-06)
We describe the role of the Schur multiplier in the structure of the p-torsion of discrete groups. More concretely, we ...

Cellular covers of local groups

Flores Díaz, Ramón Jesús; Scherer, Jérôme (Springer, 2018-12-01)
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.

El problema de la palabra en los grupos de trenzas

González-Meneses López, Juan; Flores Díaz, Ramón Jesús; Aguilar Martín, Javier (2018-06-18)
The word problem, the conjugacy problem and the isomorphism problem were three fundamental problems of group theory proposed ...

Polynomial braid combing

Flores Díaz, Ramón Jesús; González-Meneses López, Juan (Oxford University Press, 2018-01-01)
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.

K-homology and K-theory for the lamplighter groups of finite groups

Flores Díaz, Ramón Jesús; Pooya, Sanaz; Valette, Alain (London Mathematical Society, 2017-08-01)
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 ...

Homogeneity test for functional data

Flores Díaz, Ramón Jesús; Lillo Rodríguez, Rosa Elvira; Romo Urroz, Juan (Taylor & Francis, 2017-01-01)
In the context of functional data analysis, we propose new two sample tests for homogeneity. Based on some well-known depth ...

Cryptography with right-angled Artin groups

Flores Díaz, Ramón Jesús; Kahrobaei, Delaram (Polish Academy of Sciences, 2016-01-01)
In this paper we propose right-angled Artin groups as a platform for secret sharingschemes based on the efficiency (linear ...

Cellular properties of nilpotent spaces

Chachólski, Wojciech; Farjoun, Emmanuel Dror; Flores Díaz, Ramón Jesús; Scherer, Jérôme (Mathematical Sciences Publishers, 2015-10-01)
We show that cellular approximations of nilpotent Postnikov stages are always nilpotent Postnikov stages, in particular ...

Homotopy idempotent functors on classifying spaces

Castellana Vila, Natàlia; Flores Díaz, Ramón Jesús (American Mathematical Society, 2015-02-01)
Fix a prime p. Since their definition in the context of Localization Theory, the homotopy functors PBZ/p and CWBZ/p have ...

Pyramidal values

Flores Díaz, Ramón Jesús; Molina Ferragut, Elisenda; Tejada Cazorla, Juan Antonio (Springer, 2014-06-01)
We propose and analyze a new type of values for cooperative TU-games, which we call pyramidal values. Assuming that the ...

On the classifying space for proper actions of groups with cyclic torsion

Antolín Pichel, Yago; Flores Díaz, Ramón Jesús (De Gruyter, 2014-01-01)
In this paper we introduce a common framework for describing the topological part of the Baum-Connes conjecture for a wide ...

On the idempotency of some composite functors

Flores Díaz, Ramón Jesús (Springer, 2012-01-01)
We present examples of localization functors whose composition with certain cellularization functors is not idempotent, and vice versa.

The cellular structure of the classifying spaces of finite groups

Flores Díaz, Ramón Jesús; Foote, Richard M. (Springer, 2011-08-01)
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.

Nullification and cellularization of classifying spaces of finite groups

Flores Díaz, Ramón Jesús (American Mathematical Society, 2007-04-01)
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

Flores Díaz, Ramón Jesús (Mathematical Sciences Publishers, 2005-09-01)
Let G be a discrete group for which the classifying space for proper G-actions is finite-dimensional. We find a space W ...
