On some mean value results involving |zeta(1/2+ it)|

A. Ivić

Several problems involving $E(T)$ and
$E_2(T)$, the error terms in the mean square and mean fourth
moment formula for $|\zt|$, are discussed. In particular it is
proved that
$$
\int_0^T E(t)E_2(T)\d t łl T^{7/4}(łog T)^{7/2}łogłog T.
$$
