摘要：
By developing a new technique some results for the rational functions with prescribed poles and restricted zeros have been obtained. The estimated results strengthen many well known inequalities concerning the derivative and polar derivative of polynomials. (C) 2017 Elsevier Inc. All rights reserved.
