Abstract
For all q≥2q\ge 2 and for all invertible residue classes aa modulo qq, there exists a natural number that is congruent to aa modulo qq and that is the product of exactly three primes, all of which are below (1015q)5/2(10^{15}q)^{5/2}.
期刊介绍:
All articles submitted to this journal are peer-reviewed. The AMS has a single blind peer-review process in which the reviewers know who the authors of the manuscript are, but the authors do not have access to the information on who the peer reviewers are.
This journal is devoted to research articles of the highest quality in computational mathematics. Areas covered include numerical analysis, computational discrete mathematics, including number theory, algebra and combinatorics, and related fields such as stochastic numerical methods. Articles must be of significant computational interest and contain original and substantial mathematical analysis or development of computational methodology.
