Abstract

In the paper the formulas are provided for the derivatives of Cauchy-type integral \(K[u]\) which are smooth on the skeleton of the polydisk of functions \(u\). These formulas express the derivatives of the order \(m\) of \(K[u]\) through the derivatives of lower order (Theorem 2.1). They are used for estimating the smoothness of the derivatives of the Cauchy-type integral in terms of Hölder order scale (Theorem 3.1).
