摘要

Let \(\mathcal M\) M be a set of positive integers with the minimal element \(m\ge 2\) m 2 . A positive integer is called an \(\mathcal M\) M -free integer if every exponent of its prime factors is not contained in \(\mathcal M\) M . We study the distribution of \(\mathcal M\) M -free integers in the Piatetski-Shapiro sequences. Several new results of the distribution of special integers in the Piatetski-Shapiro sequences also are obtained.
