Article
![]() Lifting Semistability in Finitely Generated Ascending HNN-Extensions
(Association des Annales de l'Institut Fourier, 2023)
If a finitely generated group G maps epimorphically onto a group H, we are interested in the question: When does the ... |
Article
![]() Proper 2–equivalences between infinite ended finitely presented groups
(Mathematical Sciences Publishers, 2023)
Recall that two finitely presented groups G and H are “proper 2–equivalent” if they can be realized by finite 2–dimensional ... |
Article
![]() Weak- Z-Structures and one-relator groups
(ScienceDirect, 2022)
Motivated by the notion of boundary for hyperbolic and groups, Bestvina [2] introduced the notion of a (weak) -structure ... |
Final Degree Project
![]() Topología de grafos finitos
(2022)
The goal of this work is to prove some standard theorems on free groups by using graphs and their topology. For this, we ... |
Article
![]() A topological equivalence relation for finitely presented groups
(ScienceDirect, 2020)
In this paper, we consider an equivalence relation within the class of finitely presented discrete groups attending to ... |
Article
![]() Quasi-isometries and proper homotopy: The quasi-isometry invariance of proper 3-realizability of groups
(American Mathematical Society, 2019)
We recall that a finitely presented group G is properly 3-realizable if for some finite 2-dimensional CW-complex X with ... |
Article
![]() Relating the Freiheitssatz to the asymptotic behavior of a group
(European Mathematical Society, 2013)
We are concerned with the implications of the Freiheitssatz property for certain group presentations in terms of proper ... |
Article
![]() On manifolds with nonhomogeneous factors
(Springer, 2012)
We present simple examples of finite-dimensional connected homogeneous spaces (they are actually topological manifolds) ... |
Article
![]() Groups which are not properly 3-realizable
(European Mathematical Society, 2012)
A group is properly 3-realizable if it is the fundamental group of a compact polyhedron whose universal covering is proper ... |
Article
![]() One-relator groups and proper 3-realizability
(European Mathematical Society, 2009)
How different is the universal cover of a given finite 2-complex from a 3-manifold (from the proper homotopy viewpoint)? ... |
Article
![]() Amalgamated products and properly 3-realizable groups
(Elsevier, 2007)
In this paper, we show that the class of all properly 3-realizable groups is closed under amalgamated free products (and ... |
Article
![]() Minimal covers of open manifolds with half-spaces and the proper L-S category of product spaces
(Belgian Mathematical Society, 2002)
Classical results about the Lusternik-Schnirelmann category of product spaces have their analogues in the category of ... |
Article
