Properness and finiteness of totally geodesic submanifolds in the convex core

Minju Lee, Hee Oh

We study totally geodesic submanifolds in the convex core of geometrically finite rank-one locally symmetric manifolds. Although the infinite-volume setting can exhibit highly comp…

Dynamics and Rigidity through the Lens of Circles

Hee Oh

We report on recent developments in the dynamics and rigidity of infinite-volume homogeneous spaces, viewed through the lens of circles. By addressing four natural questions about…

Fractal closures of geodesic planes in Hitchin manifolds

Subhadip Dey, Hee Oh

Ratner's theorem implies topological rigidity of immersed totally geodesic subspaces of noncompact type in finite-volume locally symmetric spaces. In higher rank and infinite volum…

Counting totally real units and eigenvalue patterns in and in thin tubes

Hee Oh

For a vector with and , we study the "directional entropy" of two arithmetic objects: (1) the logarithmic embeddings of degree-…

Deformations of Anosov subgroups: Limit cones and Growth indicators

Subhadip Dey, Hee Oh

Let be a connected semisimple real algebraic group. We prove that limit cones vary continuously under deformations of Anosov subgroups of under a certain convexity assumpti…

Bi-Lipschitz rigidity of discrete subgroups

Richard Canary, Hee Oh, Andrew Zimmer

We obtain a bi-Lipschitz rigidity theorem for a Zariski dense discrete subgroup of a connected simple real algebraic group. As an application, we show that any Zariski dense discre…
