چکیده

Let {gt} be a nonquasiunipotent one-parameter subgroup of a connected semisimple Lie group G without compact factors; we prove that the set of points in a homogeneous spaceG/Γ (Γ an irreducible lattice inG) with bounded {gt}-trajectories has full Hausdorff dimension. Using this we give necessary and sufficient conditions for this property to hold for any Lie group G and any lattice Γ in G.

Nondense orbits of nonquasiunipotent flows and applications to Diophantine approximation Dmitry Y. Kleinbock Yale University 1996 Let G be a Lie group and Γ a lattice in G. Consider a partially hyperbolic (nonquasiunipotent) flow on the homogeneous space G/Γ. We prove that for certain classes of subsets Z of G/Γ, the set of points with orbits staying away from Z, even though it may have measure...

Nondense Orbits of Flows on Homogeneous Spaces

Let F be a nonquasiunipotent one-parameter (cyclic) subgroup of a unimodular Lie group G, Γ a discrete subgroup of G. We prove that for certain classes of subsets Z of the homogeneous space G/Γ, the set of points in G/Γ with F -orbits staying away from Z has full Hausdorff dimension. From this we derive applications to geodesic flows on manifolds of constant negative curvature.

Dani’s work on dynamical systems on homogeneous spaces

We describe some of S.G.Dani’s many contributions to the theory and applications of dynamical systems on homogeneous spaces, with emphasis on unipotent flows. S.G.Dani has written over 100 papers. They explore a variety of topics, including: • flows on homogeneous spaces – unipotent dynamics – applications to Number Theory – divergent orbits – bounded orbits and Schmidt’s game – topological orb...

Badly Approximable Systems of Affine Forms

We prove an inhomogeneous analogue of W.M. Schmidt’s (1969) theorem on the Hausdorff dimension of the set of badly approximable systems of linear forms. The proof is based on ideas and methods from the theory of dynamical systems, in particular, on abundance of bounded orbits of mixing flows on homogeneous spaces of Lie groups.
