实直线上的多项式Roth定理

A polynomial Roth theorem on the real line

Polona Durcik, Shaoming Guo, Joris Roos

摘要:

对于次数大于1的多项式$P$,我们证明了在实数的正密度子集中存在$(x,x+t,x+P(t))$形式的模式,并对$t$进行了间隙估计。这是Bourgain的一个较早结果的推广。我们的证明是一个组合的Bourgain的方法和最近的方法,最初开发的双线性希尔伯特变换沿曲线的研究。

英文摘要:

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.
