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 cert…

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…
