Synopsis

The main objective of this paper is to establish the modulus of derivative of rational functions r(z) having all its zeros in |z|≤ k ≤1 except t zeros of order α1, α2, …..., αt respectively and some other related inequalities. Besides generalizing and sharpening some well-known inequalities for the derivative of rational functions with prescribed poles, the obtained results also refine some polynomial inequalities.
