Irreducible groups and ergodicity in the boundary
Subhadip dey, Sebastian Hurtado
We show that if is a real semi-simple Lie group, and is a discrete subgroup of containing a subgroup acting ergodically (in a strong sense) on the Furstenberg bound…

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…

Anosov representations of amalgams
Subhadip Dey, Konstantinos Tsouvalas
For uniform lattices in rank 1 Lie groups, we construct Anosov representations of virtual doubles of along certain quasiconvex subgroups. We also show that virtual HNN exte…
