We consider decomposition spaces R/G that are manifold factors and admit defining sequences consisting of cubes-with-handles. Metrics on R/G constructed via modular embeddings of R/G into Euclidean spaces promote the controlled topology to a controlled geometry. The quasisymmetric parametrizability of the metric space R/G×R by R for any m ≥ 0 imposes quantitative topological constraints, in terms of the circulation and the growth of the cubes-with-handles, to the defining sequences for R/G. We… 

Uniformization of two-dimensional metric surfaces

We establish uniformization results for metric spaces that are homeomorphic to the Euclidean plane or sphere and have locally finite Hausdorff 2-measure. Applying the geometric definition of

Quasisymmetric spheres constructed over quasidisks

In this paper we provide some concrete examples of quasispheres and quasisymmetric spheres. We present two different constructions of surfaces in R over a quasidisk Ω ⊂ R. In the first construction,

Geometric function theory: the art of pullback factorization

In this paper, we develop the foundations of the theory of quasiregular mappings in general metric measure spaces. In particular, nine definitions of quasiregularity for a discrete open mapping with

Remarks on conformal modulus in metric spaces

. We give an example of an Ahlfors 3 -regular, linearly locally connected metric space homeomorphic to R 3 containing a nondegenerate continuum E with zero capacity, in the sense that the conformal

Quasispheres and metric doubling measures

Applying the Bonk-Kleiner characterization of Ahlfors 2-regular quasispheres, we show that a metric two-sphere $X$ is a quasisphere if and only if $X$ is linearly locally connected and carries a weak

Deformation and quasiregular extension of cubical Alexander maps

In this article we prove that, for an oriented PL $n$-manifold $M$ with $m$ boundary components and $d_0\in \mathbb N$, there exist mutually disjoint closed Euclidean balls and a $\mathsf

Bi-Lipschitz embedding of the generalized Grushin plane in Euclidean spaces

We show that, for all $\alpha\geq 0$, the generalized Grushin plane $\mathbb{G}_{\alpha}$ is bi-Lipschitz homeomorphic to a $2$-dimensional quasiplane in the Euclidean space $\mathbb{R}^{[\alpha

Quasiregular Ellipticity of Open and Generalized Manifolds

We study the existence of geometrically controlled branched covering maps from $$\mathbb R^3$$R3 to open $$3$$3-manifolds or to decomposition spaces $$\mathbb {S}^3/G$$S3/G, and from $$\mathbb

Quasisymmetric spheres over Jordan domains

Let $\Omega$ be a planar Jordan domain. We consider double-dome-like surfaces $\Sigma$ defined by graphs of functions of $dist( \cdot ,\partial \Omega)$ over $\Omega$. The goal is to find the right



Quasiconformality and quasisymmetry in metric measure spaces.

A homeomorphism f : X → Y between metric spaces is called quasisymmetric if it satisfies the three-point condition of Tukia and Vaisala. It has been known since the 1960’s that when X = Y = R (n ≥

Good metric spaces without good parameterizations

A classical problem in geometric topology is to recognize when a topological space is a topological manifold. This paper addresses the question of when a metric space admits a quasisymmetric

Quasiconformal maps in metric spaces with controlled geometry

This paper develops the foundations of the theory of quasiconformal maps in metric spaces that satisfy certain bounds on their mass and geometry. The principal message is that such a theory is both

Quasisymmetric nonparametrization and spaces associated with the Whitehead continuum

The decomposition space R 3 =Wh associated with the Whitehead continuum Wh is not a manifold, but the product .R 3 =Wh/ R m is homeomorphic to R 3Cm for any m 1 (known since the 1960’s). We study the

Quasisymmetric parametrizations of two-dimensional metric spheres

We study metric spaces homeomorphic to the 2-sphere, and find conditions under which they are quasisymmetrically homeomorphic to the standard 2-sphere. As an application of our main theorem we show

Strange actions of groups on spheres

In [FS] we investigated certain topological analogs of Schottky groups, called admissible actions, and their compatibility with various structures on spheres. We constructed an action ϕ : F 2 × S 3→

Finding curves on general spaces through quantitative topology, with applications to Sobolev and Poincaré inequalities

In many metric spaces one can connect an arbitrary pair of points with a curve of finite length, but in Euclidean spaces one can connect a pair of points with a lot of rectifiable curves, curves that

Cell-like closed-0-dimensional decompositions of ³ are ⁴ factors

It is proved that the product of a cell-like closed-0dimensional upper semicontinuous decomposition of R3 with a line is R4. This establishes at once this feature for all the various dogbone-inspired

Quasisymmetric parametrizations of two‐dimensional metric planes

The classical uniformization theorem states that any simply connected Riemann surface is conformally equivalent to the disk, the plane, or the sphere, each equipped with a standard conformal
