新的和积型估计

New sum product type estimates

Sergei V. Konyagin, Misha Rudnev

摘要:

新的下界涉及和,差,产品,和比率集的一组$A\subset \C$。估计涉及的总和集匹配,直到常数,一个由Solymosi获得的真正的,并通过推广他的做法得到的复平面。涉及差集的边界稍弱。他们改善了最有名的,包括案件$A\subset \R$,这也是由于Solymosi,通过结合使用Szemerédi-特罗特定理与算术组合技术。

英文摘要:

New lower bounds involving sum, difference, product, and ratio sets for a set $A\subset \C$ are given. The estimates involving the sum set match, up to constants, the one obtained by Solymosi for the reals and are obtained by generalising his approach to the complex plane. The bounds involving the difference set are slightly weaker. They improve on the best known ones, including the case $A\subset \R$, which also due to Solymosi, by means of combining the use of the Szemerédi-Trotter theorem with an arithmetic combinatorics technique.
