Equidistribution of currents under Anosov group actions
Nguyen-Bac Dang, Michael Kapovich, Mikhail Lyubich +1
We study the behavior of currents on flag-manifolds under actions of Anosov subgroups of complex semisimple Lie groups G. Given a current T of bidimension (k, k) on the full flag-m…

On cube and Cremona rigidity for higher-rank lattices
Shengyuan Zhao
For irreducible lattices in semisimple Lie groups of real rank at least , we prove a cohomological vanishing result implying that any action on a CAT(0) cube complex fixes a ver…

Decay of weighted cusp counts for congruence subgroups of over number fields
Shengyuan Zhao
For congruence subgroups commensurable with over number fields, we study cusp counts with arithmetic multiplicities. We prove that the ratio of the total weig…
