Abstract We show that the system of equations
$$ egin{align*} sum_{i=1}^{s} (x_{i}^{,j}-y_{i}^{,j}) = a_{j} quad (1 leqslant j leqslant k) end{align*} $$
has appreciably fewer solutions in the subcritical range
$s < frac 12k(k+1)$
than its homogeneous counterpart, provided that
$a_{ell }
eq 0$
for some
$ell leqslant k-1$
. Our methods use Vinogradov’s mean value theorem in combination with a shifting argument.
