Outline of Final Research Achievements

We derived the mean square formula in short intervals for an arithmetical error term by using the Tong-type truncated formula which we had already established for zeta-functions in the extended Selberg class. We applied our theorems to the study of the three-dimensional divisor problems and got the new results for the shifted convolutions and the sign changes of its arithmetical error term. Furthermore,we remade our Tong-type truncated formula in term of the exponent of the mean square of the zeta-function on the critical line.
In 1999, Hall derived the approximate functional equations for the square of the derivative of the Reimann zeta-function and other functions. By generalizing the method of Titchmarsh, we improved the estimates of Hall's error terms.
