Let v be an odd real polynomial (i.e. a polynomial of the form ). We utilize sets of iterated differences to establish new results about sets of the form where denotes the distance to the closest integer. We then apply the new Diophantine results to obtain applications to ergodic theory and combinatorics. In particular, we obtain a new characterization of weakly mixing systems as well as a new variant of Furstenberg-Sárközy theorem.

迭代差分集、丢番图近似和应用
设v是一个奇数实数多项式(即形式为)。我们利用迭代差异集来建立关于表单集的新结果 在哪里 表示到最近整数的距离。然后我们应用新的丢番图结果来获得遍历理论和组合学的应用。特别是,我们获得了弱混合系统的新特征以及 Furstenberg-Sárközy 定理的新变体。
