| Invariant measures and the set of exceptions to Littlewood's conjecture (2006) | |||||||||||
Abstract | |||||||||||
| We classify the measures on $\SL (k,\Bbb R) / \SL (k, \ZZ)$ which are invariant and ergodic under the action of the group $A$ of positive diagonal matrices with positive entropy. We apply this to prove that the set of exceptions to Littlewood's conjecture has Hausdorff dimension zero. | |||||||||||
