# ON THE FAILURE OF THE CO-HOPF PROPERTY FOR SUBGROUPS OF WORD-HYPERBOLIC GROUPS

@inproceedings{Potyagailo1999ONTF, title={ON THE FAILURE OF THE CO-HOPF PROPERTY FOR SUBGROUPS OF WORD-HYPERBOLIC GROUPS}, author={Leonid Potyagailo}, year={1999} }

We provide an example of a finitely generated subgroupH of a torsion-free word-hyperbolic group G such that H is one-ended, and H does not split over a cyclic group, and H is isomorphic to one of its proper subgroups.

Hölder Conditions for Endomorphisms of Hyperbolic Groups

- Mathematics
- 2016

It is proved that an endomorphism φ of a hyperbolic group G satisfies a Hölder condition with respect to a visual metric if and only if φ is virtually injective and Gφ is a quasiconvex subgroup of G.…

Structure of normally and finitely non-co-Hopfian groups

- Mathematics
- 2017

A group G is (finitely) co-Hopfian if it does not contain any proper (finite-index) subgroups isomorphic to itself. We study finitely generated groups G that admit a descending chain of proper normal…

Endomorphisms of Relatively Hyperbolic Groups

- MathematicsInt. J. Algebra Comput.
- 2008

The following are proved: • If G is a nonelementary relatively hyperbolic group with slender parabolic subgroups, and either G is not co-Hopfian or Out(G) is infinite, then G splits over a slender group.

A Sierpiński carpet with the co-Hopfian property

- Mathematics
- 2010

Motivated by questions in geometric group theory we define a quasisymmetric co-Hopfian property for metric spaces and provide an example of a metric Sierpiński carpet with this property. As an…

HIRSCH FOLIATIONS IN CODIMENSION GREATER THAN ONE

- Mathematics

We generalize the Hirsch construction of a smooth foliation on a 3-manifold with a unique exceptional minimal set, to obtain a method for constructing smooth foliations of arbitrary codimension with…

Geometry of infinitely presented small cancellation groups, Rapid Decay and quasi-homomorphisms

- Mathematics

We study the geometry of infinitely presented groups satisfying the small cancelation condition C'(1/8), and define a standard decomposition (called the criss-cross decomposition) for the elements of…

Genericity, the Arzhantseva-Ol’shanskii method and the isomorphism problem for one-relator groups

- Mathematics
- 2002

Abstract.We show that the isomorphism problem is solvable in at most exponential time for a class of one-relator groups which is exponentially generic in the sense of Ol’shanskii. This is obtained by…

Stable actions of groups on real trees

- Mathematics
- 1995

This paper further develops Rips's work on real trees. We study a class of actions called ‘stable’ which includes actions with trivial arc stabilizers and small actions of hyperbolic groups.

Structure and Rigidity in (Gromov) Hyperbolic Groups and Discrete Groups in Rank 1 Lie Groups II

Abstract. We borrow the Jaco-Shalen-Johannson notion of characteristic sub-manifold from 3-dimensional topology to study cyclic splittings of torsion-free (Gromov) hyperbolic groups and finitely…

In [1], B. Baumslag defined a subgroup U of a group G to be malnormal in G if gug –1 ∈ U, 1 ≠ u ∈ U, implies that g ∈ U. Baumslag considered the class of amalgamated products (A * B; U) in which U is…

Incoherent negatively curved groups

In part 1, a construction of Rips is modified so that it produces a CAT(-1) group instead of a small-cancellation group. Thus, many of the applications of Rips' construction to small-cancellation…

By considering branched coverings of piecewise Euclidean cubical complexes, the paper provides an example of a torsion free hyperbolic group containing a finitely presented subgroup which is not…
