A dynamical proof of non-arithmeticity of Jordan spectra
Hee Oh, Pratyush Sarkar
We give a dynamical proof of Benoist's non-arithmeticity theorem for Jordan spectra of Zariski dense subgroups of connected semisimple real algebraic groups. After passing to a Zar…

Dichotomy and measures on limit sets of Anosov groups
Minju Lee, Hee Oh
Let be a connected semisimple real algebraic group. For any Zariski dense Anosov subgroup , we show that a -conformal measure is supported on the limit set of if…
