Bounds on Derivatives in Compositions of Two Rational Functions with Prescribed Poles

Complex Variables 2025-02-21 v1

Abstract

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 poles, extending and refining previous results in the eld.
