多项返回时间定理的点态特征因子
Pointwise characteristic factors for the multiterm return times theorem
摘要:
本文是作者在2003年首次证明的结果的更新和扩展。本文的目的是研究已知对某些非常规平均值具有L^2-特征的因子,并证明这些因子对多维返回时间平均值具有点态特征。
英文摘要:
This paper is an update and extension of a result the authors first proved in 2003. The goal of this paper is to study factors which are known to be L^2-characteristic for certain nonconventional averages and prove that these factors are pointwise characteristic for the multidimensional return times averages.
