沿滤子的动力学概念

Dynamical notions along filters

Lorenzo Luperi Baglini, Sourav Kanti Patra, Md Moid Shaikh

摘要:

我们研究了沿几个动力学概念的过滤器的本地化。这推广和扩展了文献中已经考虑的类似局部化,例如接近0和接近幂等。研究了F-联结、分段F-联结、集合F-分段联结、F-拟中心和F-中心集的定义和基本性质,以及它们与F-一致回复点和超滤子的关系。我们还提供了上述一些概念的非标准特征,我们证明了几个非线性方程沿过滤器的划分规则性温和的一般假设。

英文摘要:

We study the localization along a filter of several dynamical notions. This generalizes and extends similar localizations that have been considered in the literature, e.g. near 0 and near an idempotent. Definitions and basic properties of F-syndetic, piecewise F-syndetic, collectionwise F-piecewise syndetic, F-quasi central and F-central sets and their relations with F-uniformly recurrent points and ultrafilters are studied. We provide also the nonstandard characterizations of some of the above notions and we prove the partition regularity of several nonlinear equations along filters under mild general assumptions.
