Abstract

We prove a non-trivial result for the,say,modified Selberg integral \modSel3(N,h)\modSel_3(N,h), of the divisor function d3(n):=abc,abc=n1d_3(n):= \sum_{a}\sum_{b}\sum_{c, abc=n}1; this integral is a slight modification of the corresponding Selberg integral, that gives the expected value of the function in short intervals. We get, in fact, \modSel3(N,h)Nh2L2\modSel_3(N,h)\ll Nh^2L^2, where L:=logNL:=\log N; furthermore, as a byproduct, we obtain indications on the way in which it may be proved the weak sixth moment of the Riemann zeta function.(This was OLD abstract)

Comments

The square-root cancellation for the modified Selberg integral of d3 is now a Conjecture. In fact,our proof of the Proposition is wrong;actually, the Proposition is too strong to be proven with present methods
