Rectangular shrinking targets for $\mathbb{Z}^m$ actions on tori: well and badly approximable systems
arXiv (Cornell University)(2023)
摘要
In this paper we investigate the shrinking target property for irrational rotations. This was first studied by Kurzweil (1951) and has received considerable interest of late. Using a new approach, we generalize results of Kim (2007) and Shapira (2013) by proving a weighted effective analogue of the shrinking target property. Furthermore, our results are established in the much wider $S$-arithmetic setting.
