Generations of Correlation Averages

Abstract: We give a general link between weighted Selberg integrals of any arithmetic functionfand averages offcorrelations in short intervals, proved by the elementary dispersion method (our version of Linnik’s method). We formulate conjectural bounds for the so-called modified Selberg integral of the divisor functionsdk(n), gauged by the Cesaro weight in the short intervaln∈x-H,x+Hand improved by these some recent results by Ivić. The same link provides, also, an unconditional improvement. Then, some remarkable condit… Show more

“…Thus, if f = g Q * 1 is gauged by a weight w in the short interval [x − H, x + H] (i.e. H = o(N ), as N → ∞), then it is natural to take the expected mean value of w H (n − x)f (n) for N < x ≤ 2N to be (compare [CopLap14])…”

“…Indeed, a basic tool for the study of the distribution of the sieve function f in short intervals is its weighted Selberg integral Observe that the trivial bound for J w,f (N, H) is N 1+ε H 2 , because f is essentially bounded. In [CopLap14] and [CopLap16] we have investigated and exploited the link between J w,f (N, H) and the correlation…”

“…H = o(N ), as N → ∞. The short intervals expected mean-value vanishes, here in the f symmetry integral, whatever the f : N → C is (and this by definition).We know (from Lemma 7 of[CL1]) that, since f H is bounded, hereafter H = o(N ),J fH , sgn (N, H) = h W H (h) N <n≤2N f H (n)f H (n − h) + O(H 3 ),where the weight W H (h) is the correlation of sgn function,[CL2], namelyW H (h) def = −H≤h 1 , h 2 ≤H h 2 −h 1 =h sgn(h 1 )sgn(h 2 ),…”
