Turan type inequalities for rational functions with pescribed poles and restricted zeros
Preeti Gupta
In this paper, we establish some inequalities for rational functions with prescribed poles having s-fold zeros at origin and also show that it implies some inequalities for polynom…

Bounds on Derivatives in Compositions of Two Rational Functions with Prescribed Poles
Preeti Gupta
This paper explores a class of rational functions r(s(z)) with degree mn, where s(z) is a polynomial of degree m. Inequalities are derived for rational functions with specified pol…
