Abstract
The polynomial approximants which retain the zero free property of a given analytic functions in the unit disk of the form (...). The convolution methods of a geometric functions that the Cesaro means of order μ retains the zero free property of the derivatives of bounded convex functions in the unit disk are used. Other properties are established.
