Vinogradov's theorem with almost equal summands

Kaisa Matomäki, James Maynard, Xuancheng Shao

Let $θ > 11/20$ . We prove that every sufficiently large odd integer $n$ can be written as a sum of three primes $n = p_{1} + p_{2} + p_{3}$ with $∣ p_{i} - n /3∣ \leq n^{θ}$ for $i \in {1, 2, 3}$ …

Gowers norms of multiplicative functions in progressions on average

Xuancheng Shao

Let $μ$ be the Möbius function and let $k \geq 1$ . We prove that the Gowers $U^{k}$ -norm of $μ$ restricted to progressions ${n \leq X : n \equiv a_{q} (mod q)}$ is $o (1)$ on average ov…

Weyl sums, mean value estimates, and Waring's problem with friable numbers

Sary Drappeau, Xuancheng Shao

In this paper we study Weyl sums over friable integers (more precisely $y$ -friable integers up to $x$ when $y = (lo g x)^{C}$ for a large constant $C$ ). In particular, we obtain an a…
