和集的多项式大性与全遍历集

Polynomial largeness of sumsets and totally ergodic sets

A. Fish

摘要:

我们证明了(\N)的TE子集(这些集合可以被看作是“非周期”集合)的具有正上密度集的和集与任何具有整数系数的多项式的值集相交。即,对于任何(A \subset \N)TE集,对于任何(p(n)\in \Z [n]:0 {p(n)} > 0,p(n)\to_{n \to \infty} \infty)和正上密度的任何子集(B \subset \N),我们有(R_p = A+B \cap p(n)|n \in \N \} \neq \emptyset)。对于(A)一个WM集(TE集的子类),我们证明了(R_p)具有较低的密度1.此外,我们得到了后者的结果的情况下,几个多项式和几个WM集的推广。

英文摘要:

We prove that a sumset of a TE subset of (\N) (these sets can be viewed as "aperiodic" sets) with a set of positive upper density intersects a set of values of any polynomial with integer coefficients., i.e. for any (A \subset \N ) a TE set, for any (p(n) \in \Z[n]: °{p(n)} > 0, p(n) \to_{n \to \infty} \infty ) and any subset (B \subset \N ) of positive upper density we have (R_p = A+B \cap \{p(n) | n \in \N \} \neq \emptyset). For (A ) a WM set (subclass of TE sets) we prove that (R_p ) has lower density 1. In addition we obtain a generalization of the latter result to the case of several polynomials and several WM sets.
