齐性空间乘积上的发散轨线

Divergent trajectories on products of homogeneous spaces

Jinpeng An, Lifan Guan, Antoine Marnat, Ronggang Shi

摘要:

本文确定了某些齐性空间乘积上具有发散轨线的点集的豪斯多夫维数。允许相对于积空间中的因子对流量进行加权。这个结果是从丢番图逼近中的对应结果导出的。在此过程中,我们引入了联合奇异矩阵元组的概念,并将奇异矩阵的维数公式推广到这种矩阵元组。

英文摘要:

In this paper, we determine the Hausdorff dimension of the set of points with divergent trajectories on the product of certain homogeneous spaces. The flow is allowed to be weighted with respect to the factors in the product space. The result is derived from its counterpart in Diophantine approximation. In doing this, we introduce a notion of jointly singular matrix tuples, and extend the dimension formula for singular matrices to such matrix tuples.
