abstract = {<p style="text-align: justify;">In the present article, we deal with the so-called overconvergence phenomenon
in $\mathbb{C}$ of a slightly modified Post-Widder operator of real variable, that is with
the extension of its approximation properties from the real axis in the complex plane.
In this sense, error estimates in approximation and a quantitative Voronovskaya-type
asymptotic formula are established.</p>},
