不变测度与Littlewood猜想的例外集
Invariant measures and the set of exceptions to Littlewood's conjecture
摘要:
对SL(k,R)/SL(k,Z)上在正对角矩阵群A作用下不变遍历的测度进行了分类.我们应用这一点来证明,一组例外的Littlewood猜想有豪斯多夫维数为零。
英文摘要:
We classify the measures on SL (k,R)/SL (k,Z) 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.
