Optimizing the Upper-Bound Constant for the Crossing Number of Polynomial Curve Systems

Hyungryul Baik

Baader, Jörg, and Parlier recently established an upper bound for the crossing number of curve systems of size on a genus surface, obtaining a leading coeffic…

Uniform Perfectness and Centers in Sublinearly Morse Boundaries

Hyungryul Baik

The --Morse boundary was introduced for CAT(0) spaces by Qing and Rafi and extended to proper geodesic spaces by Qing, Rafi, and Tiozzo. Motivated by Han and Liu's work on unifo…

Normal generators for mapping class groups

Hyungryul Baik, Dongryul M. Kim

In this chapter, we discuss normal generators for mapping class groups of surfaces. Especially, we focus on the relation between normal generation of a mapping class with its asymp…

Reconstruction of Anosov flows from infinity

Hyungryul Baik, Chenxi Wu, Bojun Zhao

Every pseudo-Anosov flow in a closed -manifold gives rise to an action of on a circle from infinity \cite{Fen12}, with a pair of invariant \…

On Translation Lengths of Pseudo-Anosov Maps on the Curve Graph

Hyungryul Baik, Changsub Kim

We show that a pseudo-Anosov map constructed as a product of the large power of Dehn twists of two filling curves always has a geodesic axis on the curve graph of the surface. We a…

Groups acting on veering pairs and Kleinian groups

Hyungryul Baik, Hongtaek Jung, KyeongRo Kim

We show that some laminar group which has an invariant veering pair of laminations is a hyperbolic 3-orbifold group. On the way, we show that from a veering pair of laminations, on…

Topological entropy of pseudo-Anosov maps on punctured surfaces vs. homology of mapping tori

Hyungryul Baik, Juhun Baik, Changsub Kim +1

We investigate the relation between the topological entropy of pseudo-Anosov maps on surfaces with punctures and the rank of the first homology of their mapping tori. On the surfac…

Reducible normal generators for mapping class groups are abundant

Hyungryul Baik, Dongryul M. Kim, Chenxi Wu

In this article, we study the normal generation of the mapping class group. We first show that a mapping class is a normal generator if its restriction on the invariant subsurface…

Random walks on mapping class groups

Inhyeok Choi, Hyungryul Baik

This survey is concerned with random walks on mapping class groups. We illustrate how the actions of mapping class groups on Teichmüller spaces or curve complexes reveal the nature…

Characterization of Fuchsian groups as laminar groups & the structure theorem of hyperbolic 2-orbifolds

Hyungryul Baik, KyeongRo Kim

Thurston and Calegari-Dunfield showed that the fundamental group of some tautly foliated hyperbolic 3-manifold acts on the circle in a distinctive way that the action preserves som…

Foliations from left orders

Hyungryul Baik, Sebastian Hensel, Chenxi Wu

We describe a construction which takes as an input a left order of the fundamental group of a manifold, and outputs a (singular) foliation of this manifold which is analogous to a…
