论文摘要

我们显示了平均值的点融合\ [\ Mathcal {a} _n f(x)= \ frac {1} {\#\#\#\#\ \#\#\#\ \ sum_n} \ sum_ {n \ n \ \ ell^1(\ Mathbb {z})$其中$ \ Mathbf {b} _n = \ MathBf {B} \ CAP [1,N] $和$ \ MATHBF {B {B} $是$ 1 $ 1 $的整数顺序n \ in \ mathbb {n} \} $。

We show the pointwise convergence of the averages \[ \mathcal{A}_N f(x) = \frac{1}{\# \mathbf{B}_N} \sum_{n \in \mathbf{B}_N} f(x + n) \] for $f \in \ell^1(\mathbb{Z})$ where $\mathbf{B}_N = \mathbf{B} \cap [1, N]$, and $\mathbf{B}$ is a $1$-regular sequence of integers, for example $\mathbf{B} = \{\lfloor n \log n \rfloor : n \in \mathbb{N}\}$.
