Zariski density of discrete subgroups via critical exponents and unitary representations

Aleksander Skenderi

Let $G$ be a connected real semisimple linear algebraic group with finite center and no compact factors, let $X$ denote its associated Riemannian symmetric space, and let $h_{\math…

Free Semigroups of Large Critical Exponent

Aleksander Skenderi

For a convergence group equipped with an expanding coarse-cocycle, we construct finitely generated free subsemigroups, which we call Bishop--Jones semigroups, of critical exponent…

Asymptotically large free semigroups in Zariski dense discrete subgroups of Lie groups

Aleksander Skenderi

Let $G$ be a connected algebraic semisimple real Lie group with finite center and no compact factors, and let $I^$ be a Zariski dense discrete subgroup of $G$ . We show that $I^$ co…
