Absolute continuity of stationary measures for random surface dynamics
Aaron Brown, Homin Lee, Davi Obata +1
We find conditions for stationary measures of random dynamical systems on surfaces having dissipative diffeomorphisms to be absolutely continuous. These conditions involve a unifor…

Positive entropy actions by higher-rank lattices
Aaron Brown, Homin Lee
We study smooth actions by lattices in higher-rank simple Lie groups. Assuming one element of the action acts with positive topological entropy, we prove a number of new rigidity r…
