amenable groups上多重遍历平均的范数收敛性

Norm convergence of multiple ergodic averages on amenable groups

Pavel Zorin-Kranich

摘要:

本文应用Walsh方法证明了多重遍历平均对任意顺从群的范数收敛性。我们得到收敛在统一Cesàro意义上的多项式行动和“三角”平均与交换同态行动。后者推广了Bergelson,McCutcheon和Zhang在两个行动的情况下的一个结果。

英文摘要:

We apply Walsh's method for proving norm convergence of multiple ergodic averages to arbitrary amenable groups. We obtain convergence in the uniform Cesàro sense for their polynomial actions and for ``triangular'' averages associated to commuting homomorphic actions. The latter generalizes a result due to Bergelson, McCutcheon, and Zhang in the case of two actions.
