Inhyeok Choi / 최인혁 (He/Him)
I am a mathematician working at KIAS (Korea Institute for Advanced Study). I received my PhD from KAIST under the supervision of Harry Hyungryul Baik.
In Spring 2026 I will be at SLMath for this event.
I am interested in various phenomena on groups with non-positive curvature. Am I a group theorist? Geometer? Topologist? Or a dynamicist?
I have no good answer. I do think about some problems in group theory, low-dimensional topology, dynamics, and probability theory. Examples include:
- interesting subgroups of some class of groups;
- statistics of objects on hyperbolic surfaces/graphs/trees/CAT(0) cube complexes;
- random walks, escape rate and asymptotic entropy;
- percolation on Cayley graphs other than Euclidean grids;
- limit sets and orbit distribution of Kleinian groups;
- Benjamini-Schramm convergence;
- bounded cohomology of hyperbolic and non-hyperbolic groups, and
- interesting examples of groups.
You can see that there is a single keyword encompassing all of these: groups. Hence I am deeply interested in groups. Put in a simpler way, I'm rather interested in objects and phenomena that entail high symmetry.
I support the statement of inclusiveness.
