方程A+B=C光滑解的计数

Counting Smooth Solutions to the Equation A+B=C

J. C. Lagarias, K. Soundararajan

摘要:

本文研究了丢番图方程A+B=C的整数解,其中A,B,C都没有大素因子.我们设置H(A,B,C)= max(|A|,|B|,|C|),并考虑对于给定的有限K,没有素因子p大于(log H(A,B,C))^K的本原解(gcd}(A,B,C)=1)。在广义黎曼假设(GRH)成立的假设下,我们证明了对于任意K > 8,存在无穷多个这样的原始解,其素因子不大于(log H(A,B,C))^K.在这个范围内,我们得到了这样的适当加权原始解的数量的渐近公式。

英文摘要:

This paper studies integer solutions to the Diophantine equation A+B=C in which none of A, B, C have a large prime factor. We set H(A, B,C) = max(|A|, |B|, |C|), and consider primitive solutions (gcd}(A, B, C)=1) having no prime factor p larger than (log H(A, B,C))^K, for a given finite K. On the assumption that the Generalized Riemann hypothesis (GRH) holds, we show that for any K > 8 there are infinitely many such primitive solutions having no prime factor larger than (log H(A, B, C))^K. We obtain in this range an asymptotic formula for the number of such suitably weighted primitive solutions.
