  "abstract": "Let $\\Delta(x)$ denote the error term in the Dirichlet divisor problem, and $E(T)$ the error term in the asymptotic formula for the mean square of $|\\zeta(1/2 + it)|$. If $E^*(t) = E(t) - 2\\pi\\Delta^*(t/(2\\pi))$ with $\\Delta^*(x) = - \\Delta(x) +2\\Delta(2x)- {1\\over2}\\Delta(4x)$, then we obtain $$ \\int_0^T(E^*(t))^4 dt \\ll_\\epsilon T^{16/19+varepsilon}$$, which is the first non-trivial bound for higher moments of $E^*(t)$. The method of proof also provides an upper bound for sums of fourth powers of mean square integrals of $|\\zeta(1/2 + it)|$ over well-spaced points. This, in turn, yields a new proof of the twelfth moment estimate for $|\\zeta(1/2 + it)|$. Among the chief ingredients in the proof is a recent result of Robert--Sargos on the distribution of four square roots of integers, plus an approach of M. Jutila that involves the use of Airy integrals to deal with the ensuing exponential sums.",
