Sažetak
We prove that the sequence of averaged quantities
$\int_{\R^m}u_n(t,\mx,\my) v(\my)d\my$ is strongly precompact in
$\Ldl\Rjpd$, where $v\in \Ldc{\R^m}$, and $u_n\in
\Ld{\Rjpd\times \R^m}$ are solutions to strictly
parabolic transport equations with flux explicitly depending on
space and time. In order to obtain the result, we use a recently introduced parabolic variant of H-measures.
