Abstract:We obtain a new upper bound for the sum Σ hH Δ k (N, h) when 1 ≤ HN, k ∈ ℕ, k ≥ 3, where Δ k (N, h) is the (expected) error term in the asymptotic formula for Σ N<n≤2N d k (n)d k (n + h), and d k (n) is the divisor function generated by ζ(s) k . When k = 3, the result improves, for HN 1/2, the bound given in a recent work of Baier, Browning, Marasingha and Zhao, who dealt with the case k = 3.
