。对于一个大于1次的多项式P,我们证明了形式为(x, x + t, x + P (t))的模式的存在性,并在实数的正密度子集上对t有间隙估计。这是布尔甘先前的一个结果的推广。我们的证明结合了布尔甘的方法和最近的方法,这些方法最初是为研究沿曲线的双线性希尔伯特变换而开发的。
. For a polynomial P of degree greater than one, we show the existence of patterns of the form ( x, x + t, x + P ( t )) with a gap estimate on t in positive density subsets of the reals. This is an extension of an earlier result of Bourgain. Our proof is a combination of Bourgain’s approach and more recent methods that were originally developed for the study of the bilinear Hilbert transform along curves.
