  We prove an asymptotic formula for the shifted convolution of the divisor
functions $d_3(n)$ and $d(n)$, which is uniform in the shift parameter and
which has a power-saving error term. The method is also applied to give
analogous estimates for the shifted convolution of $d_3(n)$ and Fourier
coefficents of holomorphic cusp forms. These asymptotics improve previous
results obtained by several different authors.
