Benjamini--Schramm convergence of arithmetic locally symmetric spaces
MikoÅaj FrÄ czyk, Sebastian Hurtado, Jean Raimbault
We prove that the thin parts of arithmetically defined locally symmetric space take up a negligible part of their volume and deduce asymptotic results on their Betti numbers.
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 bou…
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…
A strong height gap theorem for
Mikhail Belolipetsky, Sebastian Hurtado
The height gap theorem states that the finite subsets of matrices generating non-virtually solvable groups have normalized height bounded below by a constant.…
