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…

Rigidity of convex co-compact diagonal actions
Subhadip Dey, Beibei Liu
Kleiner-Leeb and Quint showed that convex subsets in higher-rank symmetric spaces are very rigid compared to rank 1 symmetric spaces. Motivated by this, we consider convex subsets…

Remarks on discrete subgroups with full limit sets in higher rank Lie groups
Subhadip Dey, Sebastian Hurtado
We show that real semi-simple Lie groups of higher rank contain (infinitely generated) discrete subgroups with full limit sets in the corresponding Furstenberg boundaries. Addition…
