Maximising the number of solutions to linear equations

Žarko Ranđelović, Xuancheng Shao, Max Wenqiang Xu +2

We study the asymptotically maximal possible number of integer solutions to the linear equation with a fixed choice of and variables $x, y,…

Distribution of random multiplicative functions in short intervals, with proper normalization

Adam J. Harper, Kannan Soundararajan, Max Wenqiang Xu

We determine the limiting distribution of partial sums of a Steinhaus random multiplicative function over short intervals , where $y \rightar…

Extreme values of Dirichlet polynomials with multiplicative coefficients

Max Wenqiang Xu, Daodao Yang

We study extreme values of Dirichlet polynomials with multiplicative coefficients, namely \[D_N(t) : = D_{f,\, N}(t)= \frac{1}{\sqrt{N}} \sum_{n\leqslant N} f(n) n^{it}, \] where $…

Central limit theorems for random multiplicative functions

Kannan Soundararajan, Max Wenqiang Xu

A Steinhaus random multiplicative function is a completely multiplicative function obtained by setting its values on primes to be independent random variables distribute…

A polynomial with a root mod for every has a real root

Rodrigo Angelo, Max Wenqiang Xu

We prove that if a polynomial has a root mod for every large prime , then it has a real root. As an application, we show that the primes can't be covered by finitely many po…

On product sets of arithmetic progressions

Max Wenqiang Xu, Yunkun Zhou

We prove that the size of the product set of any finite arithmetic progression satisfies \[|\mathcal A \cdot \mathcal A| \ge \frac{|\mathcal A|^2}{(…

Discrepancy in modular arithmetic progressions

Jacob Fox, Max Wenqiang Xu, Yunkun Zhou

Celebrated theorems of Roth and of Matoušek and Spencer together show that the discrepancy of arithmetic progressions in the first positive integers is . We study t…

Mixing time of fractional random walk on finite fields

Jimmy He, Huy Tuan Pham, Max Wenqiang Xu

We study a random walk on defined by if , and if , where are inde…

Multicolor list Ramsey numbers grow exponentially

Jacob Fox, Xiaoyu He, Sammy Luo +1

The list Ramsey number , recently introduced by Alon, Bucić, Kalvari, Kuperwasser, and Szabó, is a list-coloring variant of the classical Ramsey number. They showed…

A note on the Erdős distinct subset sums problem

Quentin Dubroff, Jacob Fox, Max Wenqiang Xu

We present two short proofs giving the best known asymptotic lower bound for the maximum element in a set of positive integers with distinct subset sums.

Irreducibility of random polynomials of bounded degree

Huy Tuan Pham, Max Wenqiang Xu

It is known that random monic integral polynomials of bounded degree and integral coefficients distributed uniformly and independently in are irreducible over $\mathbb…
