The distribution of values of L(1, χ d )
TL;DR: In this article, the authors compare the distribution of values of L(1, χd) as d varies over all fundamental discriminants with |d| ≤ x, and give asymptotics for the probability that L( 1, εd) exceeds eγτ, and the probability of ε d ≤ π2 6 1 eγ τ uniformly in a wide range of τ.
Journal ArticleDOI
Defect zero p-blocks for finite simple groups
Andrew Granville,Ken Ono,Ken Ono +2 more
TL;DR: In this paper, it was shown that every non-negative integer can be written as the sum of four squares, for any t ≥ 17, and the only case with t < 17, that was not covered in previous work, was the case t = 13.
Smooth numbers: computational number theory and beyond
TL;DR: The analysis of many number theoretic algorithms turns on the role played by integers which have only small prime factors; such integers are known as "smooth numbers" as mentioned in this paper, and it has turned out to be important to have accurate estimates for the number of smooth numbers in various sequences.

Large character sums: Pretentious characters and the Pólya-Vinogradov theorem
TL;DR: For characters of odd, bounded order, Montgomery and Vaughan as mentioned in this paper showed that the Polya-Vinogradov inequality may be sharpened assuming the Generalized Riemann Hypothesis.
