On sums of integrals of powers of the zeta-function in short intervals

The modified Mellin transform ${\cal Z}k(s) = \int_1^\infty |\zeta({1\over2}+ix|^{2k}x^{-s}{\rm d} x$($k\ge1$isafixedinteger,$s = \sigma + it$)isusedtoobtainestimatesfor$$ \sum{r=1}^R\int_{t_r-G}^{t_r+G}|\zeta(1/2+it)|^{2k}{\rm d} t\quad(T < t_1 <

… < t_R < 2T), $$where$t_{r+1} - t_r \ge G (r =1,…, R-1), T^\epsilon \le G \le T^{1-\epsilon$. These results can be used to derive bounds for the moments of }|\zeta(1/2+it)|.
