摘要:

This paper is a continuation of [3] where a parametric representation of Charzyński polynomials, i.e. polynomials being inverses of functions of the familiar classShas been given. By means of this parametric representation sharp bounds for coefficients as well as a sharp lower estimate of zeros of the derivative for Charzyński polynomials of fourth degree have been established.
