abstract = {<p style="text-align: justify;">On the basis of the estimates for the regularized Green&#39;s
functions with memory terms, optimal order $L^∞$-error estimates
are established for the nonFickian flow of fluid in porous media by
means of a mixed Ritz-Volterra projection. Moreover, local $L^∞$-superconvergence estimates for the velocity along the Gauss
lines and for the pressure at the Gauss points are derived for the mixed
finite element method, and global $L^∞$-superconvergence estimates
for the velocity and the pressure are also investigated by virtue of an
interpolation post-processing technique. Meanwhile, some useful
a-posteriori error estimators are presented for this mixed finite
element method.</p>},
