The two-point Chowla conjecture (ordinary averages)

There is an absolute c>0c>0 such that for all fixed integers a1,a2≥1a_1,a_2\ge1, b1,b2≥0b_1,b_2\ge0 with a1b2≠a2b1a_1b_2\ne a_2b_1, ∣∑n≤Xλ(a1n+b1)λ(a2n+b2)∣≤Ca,bX/(log⁡X)c\left|\sum_{n\le X}\lambda(a_1n+b_1)\lambda(a_2n+b_2)\right|\le C_{a,b}X/(\log X)^c for every real X≥3X\ge3. With a1=a2=1a_1=a_2=1, b1=0b_1=0, b2=hb_2=h this is the ordinary two-point Chowla conjecture with a power-of-log saving. Constants are ineffective, and coefficients may not grow with XX. Nothing is proved for three or more points.
