Quasisymmetric universality, quasi-isometric classification and topological rigidity of Kleinian groups

Peter Haïssinsky, Yusheng Luo

We study the quasisymmetric classification of limit sets of Kleinian groups and obtain a characterization of those geometrically finite limit sets that are quasisymmetrically unive…

Circle packings, renormalizations and subdivision rules

Yusheng Luo, Yongquan Zhang

In this paper, we use iterations of skinning maps on Teichmüller spaces to study circle packings and develop a renormalization theory for circle packings whose nerves satisfy certa…

Polynomials with core entropy zero

Yusheng Luo, Insung Park

This paper studies polynomials with core entropy zero. We give several characterizations of polynomials with core entropy zero. In particular, we show that a degree d post-critical…

On Deformation Space Analogies between Kleinian Reflection Groups and Antiholomorphic Rational Maps

Russell Lodge, Yusheng Luo, Sabyasachi Mukherjee

In a previous paper, we constructed an explicit dynamical correspondence between certain Kleinian reflection groups and certain anti-holomorphic rational maps on the Riemann sphere…

On geometrically finite degenerations II: convergence and divergence

Yusheng Luo

In this paper, we study quasi post-critically finite degenerations for rational maps. We construct limits for such degenerations as geometrically finite rational maps on a finite t…

On geometrically finite degenerations I: boundaries of main hyperbolic components

Yusheng Luo

In this paper, we develop a theory on the degenerations of Blaschke products to study the boundaries of hyperbolic components. We give a combinatorial classificatio…

Circle packings, kissing reflection groups and critically fixed anti-rational maps

Russell Lodge, Yusheng Luo, Sabyasachi Mukherjee

In this paper, we establish an explicit correspondence between kissing reflection groups and critically fixed anti-rational maps. The correspondence, which is expressed using simpl…

On hyperbolic rational maps with finitely connected Fatou sets

Yusheng Luo

In this paper, we study hyperbolic rational maps with finitely connected Fatou sets. We construct models of post-critically finite hyperbolic tree mapping schemes for such maps, ge…

Trees, length spectra for rational maps via barycentric extensions and Berkovich spaces

Yusheng Luo

In this paper, we study the dynamics of degenerating sequences of rational maps on Riemann sphere using -trees. Given a sequence of degenerating rati…

Limits of rational maps, R-trees and barycentric extension

Yusheng Luo

In this paper, we show that one can naturally associate a limiting dynamical system on an -tree to any degenerating sequence of rational maps $f_n: \hat…

On the inhomogeneity of the Mandelbrot set

Yusheng Luo

We will show the Mandelbrot set is locally conformally inhomogeneous: the only conformal map defined in an open set intersecting and satisfying $f(U\cap\pa…

Moser's Shadow Problem

Jeffrey C. Lagarias, Yusheng Luo, Arnau Padrol

Moser's shadow problem asks to estimate the shadow function , which is the largest number such that for each bounded convex polyhedron with vertices in $…

Weakly Circle-Preserving Maps in Inversive Geometry

Joel C. Gibbons, Yusheng Luo

Let S^n be the standard n-sphere embedded in R^{n+1}. A mapping T: S^n \to S^n, not assumed continuous or even measurable, nor injective, is called weakly circle-preserving if the…

Colorings of the n-sphere and inversive geometry

Joel C. Gibbons, Yusheng Luo

This paper shows that in dimensions n \geq 2 for any partition of the set of points in the standard n-sphere \sum_{i=0}^n x_i^2 =1 in R^{n+1} into (n+3) or more nonempty sets, ther…
