Abstract
We prove that the set of singular vectors in , , has Hausdorff dimension and that the Hausdorff dimension of the set of -Dirichlet improvable vectors in is roughly plus a power of between and . As a corollary, the set of divergent trajectories of the flow by acting on has Hausdorff codimension . These results extend the work of the first author.
