abstract = {<p style="text-align: justify;">For the approximation in $L_p$-norm, we determine the weakly asymptotic
orders for the simultaneous approximation errors of Sobolev classes by piecewise cubic Hermite interpolation with equidistant knots. For $p = 1$, $∞$, we obtain its values.
By these results we know that for the Sobolev classes, the approximation errors by
piecewise cubic Hermite interpolation are weakly equivalent to the corresponding
infinite-dimensional Kolmogorov widths. At the same time, the approximation errors of derivatives are weakly equivalent to the corresponding infinite-dimensional
Kolmogorov widths.</p>},
