On the topology of locally 2-connected Peano continua
(Rocky Mountain Mathematics Consortium, 2012)
Several recent results by Thomassen ([23 The locally connected compatc metric spaces embeddable in the plane, Combinatorica 24 (2004), 699-718, 24] Classification of locally 2-connected compact metric spaces, Combinatorica ...

Critical and forcing sets related to the autotopism group of a Latin square
(2006)
In Cryptography, critical sets of any Latin square L can be used to get the access structure of a secret sharing scheme [2, 6] having triples of L as shares. In such a scheme, further information about the symmetry of L ...

Homotopy in digital spaces
(Elsevier, 2003-01-15)
The main contribution of this paper is a new “extrinsic” digital fundamental group that can be readily generalized to define higher homotopy groups for arbitrary digital spaces. We show that the digital fundamental group ...

(k, µ)-Espacios de Curvatura Ø-Seccional constante generalizados
(2011)
A lo largo de los años, numerosos autores han estudiado la forma del tensor de curvatura de una variedad Riemanniana para intentar clasificarla. Buena parte de los trabajos que han aparecido sobre la materia son los que ...

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 time) of the word problem. Inspired by previous work of Grigoriev-Shpilrain in the context of ...

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 such that for any such G, the classifying space BG for proper G-bundles has the homotopy type of the ...

Superando barreras a base de ingenio
(2012)
No hay la menor duda de que la mujer ha estado siempre muy discriminada con respecto al varón en el papel a desempeñar en todas las civilizaciones que se han desarrollado a lo largo de la historia, no comenzando a tener ...

The Gauss-Landau-Hall problem on Riemannian surfaces
(AIP Publishing, 2005)
We introduce the notion of Gauss-Landau-Hall magnetic field on a Riemannian surface. The corresponding Landau-Hall problem is shown to be equivalent to the dynamics of a massive boson. This allows one to view that problem ...
