On a Goldbach-type problem for the Liouville function

Number Theory 2024-05-03 v2

Abstract

Let λ\lambda denote the Liouville function. We show that for all sufficiently large integers NN, the (non-trivial) convolution sum bound 1n<Nλ(n)λ(Nn)<N1 \left|\sum_{1 \leq n < N} \lambda(n) \lambda(N-n)\right| < N-1 holds. This (essentially) answers a question posed at the 2018 AIM workshop on Sarnak's conjecture.
