Generalized Chowla's conjecture for weighted Möbius correlations

Let (h1,h2)(h_1,h_2) be a fixed admissible 22-tuple. For a positive integer nn and y2y\ge2, let ω+(n,y)\omega_+(n,y) and ω(n,y)\omega_-(n,y) count prime divisors of nn that are respectively at least yy and less than yy. On squarefree integers define

τκ1,κ2±(n,y)=κ1ω(n,y)κ2ω+(n,y).\tau^{\pm}_{\kappa_1,\kappa_2}(n,y)=\kappa_1^{\omega_-(n,y)}\kappa_2^{\omega_+(n,y)}.

Generalized Chowla's conjecture. For fixed 0κ1<κ20\le\kappa_1<\kappa_2 and y=exp((logx)δ)y=\exp((\log x)^\delta) with fixed 0<δ<10<\delta<1,

N/2nNμ(n+h1)μ(n+h2)τκ1,κ2±(n+h1,y)τκ1,κ2±(n+h2,y)=o(N/2nNτκ1,κ2±(n+h1,y)τκ1,κ2±(n+h2,y)).\sum_{N/2\le n\le N}\mu(n+h_1)\mu(n+h_2)\tau^{\pm}_{\kappa_1,\kappa_2}(n+h_1,y)\tau^{\pm}_{\kappa_1,\kappa_2}(n+h_2,y)=o\left(\sum_{N/2\le n\le N}\tau^{\pm}_{\kappa_1,\kappa_2}(n+h_1,y)\tau^{\pm}_{\kappa_1,\kappa_2}(n+h_2,y)\right).

This asserts cancellation of two-point Möbius correlations after applying the specified preliminary-sieving weights. The source proposes it as a more general weighted form of Chowla's conjecture and provides no proof or resolution.
