On the divisor function and the Riemann zeta-function in short intervals
We obtain, for T ε ≤ U = U ( T )≤ T 1/2− ε , asymptotic formulas for where Δ( x ) is the error term in the classical divisor problem, and E ( T ) is the error term in the mean square formula for .

Summary: | We obtain, for
T

≤

=

1/2−
ε
, asymptotic formulas for
where Δ(
x
) is the error term in the classical divisor problem, and
E
(
T
) is the error term in the mean square formula for
. Upper bounds of the form
O
ε
(
T
1+
ε
U

) for the above integrals with biquadrates instead of square are shown to hold for
T

≪

. The connection between the moments of
E
(

)−
E
(

) and
is also given. Generalizations to some other number-theoretic error terms are discussed. |
