Abstract

We give an improved bound on the famed sum-product estimate in a field of residue class modulo pp (Fp\mathbb{F}_{p}) by Erd\H{o}s and Szemeredi, and a non-empty set AFpA \subset \mathbb{F}_{p} such that: max{A+A,AA}min{A15/14max{1,A1/7p1/14}(logA)2/7,A11/12p1/12(logA)1/3}, \max \{|A+A|,|A A|\} \gg \min \left\{\frac{|A|^{15 / 14} \max \left\{1,|A|^{1 / 7} p^{-1 / 14}\right\}}{(\log |A|)^{2 / 7}}, \frac{|A|^{11 / 12} p^{1 / 12}}{(\log |A|)^{1 / 3}}\right\}, and more importantly: max{A+A,AA}A15/14(logA)2/7.\max \{|A+A|,|A A|\} \gg \frac{|A|^{15 / 14}}{(\log |A|)^{2 / 7}}.

Comments

The note was submitted as part of a larger portfolio, which is where the term "improved" comes from, however, this has caused confusion as it seems to present itself as improving the current standing of the problem as a whole
