| dc.description.abstract | In this paper, we establish lower estimates for the modulus of the values of f(z) on boundary of unit disc. For the function f(z) = 1 + c1z + c2z2 +… defined in the unit disc such that f(z) ? N (?) assuming the existence of angular limit at the boundary point b, the estimations below of the modulus of angular derivative have been obtained at the boundary point b with f(b) = ?. Moreover, Schwarz lemma for class N (?) is given. The sharpness of these inequalities has been proved. © Bülent Nafi Örnek, 2017. | en_US |
