Bu çalışmada, önce ,12, de birim diskte polinomların maksimum modülleri için ispatlanan eşitsizliğin, herhangi bir R yarıçaplı disk için de geçerli olduğu gösterildi. z=0 noktası polinomların katlı kökü olması durumunda , ve f(0)=0 , f(a)=a^q,f(-a)=-a^q olan f:C---C ünivalent polinomlar için, bu eşitsizliğin farklı formları elde edilmiştir. Ayrıca ,ünivalent polinom fonksiyonlar için bu eşitsizliklerden tamamen farklı yeni eşitsizlikler hem birim diskte hem de herhangi bir R yarıçaplı bir diskte elde edilmiştir.

In this work, we first show that the inequality, established in the unit disc for maximum modulus of polynomial functions ,12, also holds for any disc of radius R . In the case where polynomials have z=0 as a multiple root, and also for the univalent polynomial functions f:C---C with f(0)=0 ,f(a=a^q , f(-a) =-a^q ,we obtain different forms of this inequality. Then we attain quite distinct new inequalities for univalent polynomial functions in both the unit disc and disc of an arbitrary radius R.
