Prime Orbit Theorems with Multi-Dimensional Constraints for Axiom A Flows.
The Circle Problem on Surfaces of Variable Negative Curvature.
Orbit counting for some discrete groups acting on simply connected manifolds with negative curvature.
Linear actions of free groups
In this paper we study dynamical properties of linear actions by free groups via the induced action on projective space. This point of view allows us to introduce techniques from Thermodynamic Formalism. In particular, we obtain estimates on the growth of orbits and their limiting distribution on projective space.
