Bounded orbits for flows on homogeneous spaces
Abstract:
I will discuss the abundance of bounded orbits for
flows on homogeneous spaces of
Lie groups. A simple example is given by bounded orbits
for the geodesic flow on the
modular surface. The study of these orbits is closely connected to Diophantine
approximation. Joint work with M. Einsiedler and B. Lytle.
