Logarithmic Chowla conjecture

Let λ\lambda be the Liouville function. For every tNt\in\mathbb{N} and every collection of distinct natural numbers h1,,hth_1,\ldots,h_t, logarithmic Chowla conjecture. One has

limNEnNlogλ(n+h1)λ(n+ht)=0.\lim_{N\rightarrow\infty}\mathbb{E}^{\log}_{n\leq N}\lambda(n+h_1)\cdots\lambda(n+h_t)=0.

This is the logarithmically averaged Chowla correlation statement and is asserted in the source to be equivalent to the tt-Fourier uniformity conjecture for every tt. The general statement remains open.
