关于和积猜想的能量变式

On The Energy Variant of the Sum-Product Conjecture

Misha Rudnev, Ilya D. Shkredov, Sophie Stevens

摘要:

我们证明了新的指数的能量版本的Erdens-Szemerédi和产品猜想,提出了Bessel和Wooley。它们与以前为问题的标准制定所建立的里程碑值相匹配,无论是对于一般领域还是实数或复数的特殊情况,并且似乎是目前可用技术中可达到的最佳值。进一步得到了加法移位的乘性能量和Elekes与Ruzsa的“少和多积”不等式的能量加强形式。后者的不等式使我们能够获得一个轻微的改善,国家的最先进的和产品指数的实数由于Konyagin和第二作者,高达$\frac{4}{3}+\frac{1}{1509}$。给出了能量估计在素剩余域算术增长问题中的一个应用。

英文摘要:

We prove new exponents for the energy version of the Erdős-Szemerédi sum-product conjecture, raised by Balog and Wooley. They match the previously established milestone values for the standard formulation of the question, both for general fields and the special case of real or complex numbers, and appear to be the best ones attainable within the currently available technology. Further results are obtained about multiplicative energies of additive shifts and a strengthened energy version of the "few sums, many products" inequality of Elekes and Ruzsa. The latter inequality enables us to obtain a minor improvement of the state-of the art sum-product exponent over the reals due to Konyagin and the second author, up to $\frac{4}{3}+\frac{1}{1509}$. An application of energy estimates to an instance of arithmetic growth in prime residue fields is presented.
