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
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
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
TLDR
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
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
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
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
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
Endomorphisms of Kleinian groups
Abstract. ((without abstract))
Coset Enumeration for certain Infinitely Presented Groups
TLDR
This algorithm shows that the subgroup membership problem for finite index subgroups in a finitely $L$-presented group is decidable.

Stable actions of groups on real trees
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
The Free Product of Two Groups with a Malnormal Amalgamated Subgroup
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
