On the random Chowla conjecture

Oleksiy Klurman, Ilya D. Shkredov, Max Wenqiang Xu

We show that for a Steinhaus random multiplicative function $f : N \to D$ and any polynomial $P (x) \in Z [x]$ of $deg P \geq 2$ which is not of the form $…

Mixing time of fractional random walk on finite fields

Jimmy He, Huy Tuan Pham, Max Wenqiang Xu

We study a random walk on $F_{p}$ defined by $X_{n + 1} = 1/ X_{n} + ε_{n + 1}$ if $X_{n} \neq = 0$ , and $X_{n + 1} = ε_{n + 1}$ if $X_{n} = 0$ , where $ε_{n + 1}$ are inde…

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 $n$ positive integers with distinct subset sums.
