(Non)-escape of mass and equidistribution for horospherical actions on trees
Corina Ciobotaru, Vladimir Finkelshtein, Cagri Sert
Let be a large group acting on a biregular tree and a geometrically finite lattice. In an earlier work, the authors classified orbit closures of the action of the…

Measure rigidity for horospherical subgroups of groups acting on trees
Corina Ciobotaru, Vladimir Finkelshtein, Cagri Sert
We investigate analogues of some of the classical results in homogeneous dynamics in non-linear setting. Let be a closed subgroup of the group of automorphisms of a biregular t…
