单参数幂幺流的对数律

Logarithm laws for one parameter unipotent flows

Dubi Kelmer, Amir Mohammadi

摘要:

证明了具有$G=\SL_2(\bbR)^{r_1}\times\SL_2(\bbC)^{r_2}$和$Γ\subseteq G$不可约非均匀格的齐次空间$Γ\bs G$上幂幺流的对数律和收缩目标性质。我们的方法依赖于某些估计的规范(不完整)θ系列在这种情况下。

英文摘要:

We prove logarithm laws and shrinking target properties for unipotent flows on the homogenous space $Γ\bs G$ with $G=\SL_2(\bbR)^{r_1}\times\SL_2(\bbC)^{r_2}$ and $Γ\subseteq G$ an irreducible non-uniform lattice. Our method relies on certain estimates for the norms of (incomplete) theta series in this setting.
