A topological equivalence relation for finitely presented groups
(ScienceDirect, 2020-01-07)In this paper, we consider an equivalence relation within the class of finitely presented discrete groups attending to ...

Amalgamated products and properly 3-realizable groups
(Elsevier, 2007-01)In this paper, we show that the class of all properly 3-realizable groups is closed under amalgamated free products (and ...

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 ...

Lifting Semistability in Finitely Generated Ascending HNN-Extensions
(Association des Annales de l'Institut Fourier, 2023-07-03)If a finitely generated group G maps epimorphically onto a group H, we are interested in the question: When does the ...

Minimal covers of open manifolds with half-spaces and the proper L-S category of product spaces
(Belgian Mathematical Society, 2002-09)Classical results about the Lusternik-Schnirelmann category of product spaces have their analogues in the category of ...

On manifolds with nonhomogeneous factors
(Springer, 2012-06)We present simple examples of finite-dimensional connected homogeneous spaces (they are actually topological manifolds) ...

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)? ...

Proper 2–equivalences between infinite ended finitely presented groups
(Mathematical Sciences Publishers, 2023-03-27)Recall that two finitely presented groups G and H are “proper 2–equivalent” if they can be realized by finite 2–dimensional ...

Quasi-isometries and proper homotopy: The quasi-isometry invariance of proper 3-realizability of groups
(American Mathematical Society, 2019-04-01)We recall that a finitely presented group G is properly 3-realizable if for some finite 2-dimensional CW-complex X with ...

Weak- Z-Structures and one-relator groups
(ScienceDirect, 2022-07-22)Motivated by the notion of boundary for hyperbolic and groups, Bestvina [2] introduced the notion of a (weak) -structure ...
