Abode, a creature grim;

Coiled up in the waters dim.

We prove that Cannon–Thurston maps are well–deﬁned (that is, subgroup inclusion induces a map of the boundaries) for heavily distorted free subgroups inside the family of hyperbolic groups known as hyperbolic hydra.
Cannon-Thurston maps, subgroup distortion, and hyperbolic hydra
Hyperbolic hydra have Cannon–Thurston maps ∂ Λk → ∂ Γk for all k .
Cannon-Thurston maps, subgroup distortion, and hyperbolic hydra
For all k ≥ 2, the modulus of continuity ǫ (δ) for the Cannon–Thurston map ∂ Λk → ∂ Γk for hyperbolic hydra grows at least like 1/n when δ grows like 1/A k (n ).
Cannon-Thurston maps, subgroup distortion, and hyperbolic hydra
The third will allow us to reinterpret Lemma 3.1 (as Corollary 3.3) in a manner well suited to analyzing hyperbolic hydra.
Cannon-Thurston maps, subgroup distortion, and hyperbolic hydra
In this section we will show that Cannon–Thurston maps for hyperbolic hydra are well–deﬁned.
Cannon-Thurston maps, subgroup distortion, and hyperbolic hydra
Recall the map Φ from the hyperbolic hydra group Γk to the hydra group G k deﬁned by a i 7→ a max{1,i } , b j 7→ 1 and t 7→ t for all i , j .

It is shown that the Hydra groups as well as certain of their generalizations and quotients are, in the main, residually torsion-free nilpotent.
On residual properties of generalized Hydra groups
These Hydra groups are inﬁnite cyclic extensions of ﬁnitely generated free groups and so are seemingly closely related to free groups, although their ﬁnitely generated subgroups have at most linear distortion.
On residual properties of generalized Hydra groups
The Hydra groups can be viewed as special cases of one-relator groups deﬁned by leftnormed commutators of various weights in disjoint sets of variables.
On residual properties of generalized Hydra groups
There are a number of variations of Theorem 2.1 which involve certain quotients of the Hydra groups, which consist of groups deﬁned by more than a single relation.
On residual properties of generalized Hydra groups
To begin with we will need to prove that the centralizer of the element a in the Hydra group Gk is generated by a.
