on some generalisations of brown s conjecture

Abstract

Summary: Let \(P\) be a complex polynomial of the form \(P(z)=z\prod_{k=1}^{n-1}(z-z_k)\), where \(|z_k|\geq 1\), \(1\leq k\leq n\) then \(P'(z)\neq 0\). If \(|z|<\frac 1n\). In this paper, we present some interesting generalisations of this result.
