An Application of Schwarz Lemma for Analytic Functions in the Unit Disc
Örnek B.N.; Akyel T. (American Institute of Physics Inc., 2022)The aim of this paper is to introduce the class of the analytic functions called P and to investigate the various properties of the functions belonging this class. We present a different version of Schwarz Lemma and some ... -
Applications of Jack’s Lemma for the holomorphic functions
Aydınoğlu S.; Örnek B.N. (Institute of Mathematics, 2018)In this paper, we give some results on (Formula presented) for certain classes of holomorphic functions on the unit disc U = {z: |z| < 1} and on ?U = {z: |z| = 1}. For the function f(z) = z+c 2 z 2 +c 3 z 3 +… defined ... -
The carathéodory inequality on the boundary for holomorphic functions in the unit disc
Örnek B.N. (B. I. Verkin Institute for Low Temperature Physics and Engineering, 2016)In this paper, a boundary version of the Carathéodory inequality is studied. For the function f(z), defined in the unit disc with f(0) = 0, ?f(z) ? A, we estimate a modulus of angular derivative at the boundary point z0, ... -
Some estimates for angular derivative at the boundary
Örnek B.N. (Institute of Mathematics and Computer Science of the Academy of Sciences of Moldova, 2017)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 ... -
Some remarks for certain subclasses of meromorphic 1 ? valent functions
Örnek B.N. (Transilvania University of Brasov 1, 2017)In this paper, a boundary version of the Schwarz lemma for classes N(?) is investigated. For the function (Formula Presented) defined in the punctured unit disc D = {z ? ?: 0 < |z| < 1} such that f(z) ? N(?), we estimate ... -
SOME REMARKS ON ANALYTIC FUNCTIONS CONCERNED WITH JACK’S LEMMA
Atli G.; Örnek B.N. (Canadian University of Dubai, 2021)In this paper, we give estimates of the Schwarz lemma in a novel class M (b) of analytical functions in the unit disc. The sharpness of some of the presented in equalities has also been shown. © 2021, Canadian University ... -
SOME RESULTS ON THE BEHAVIOUR OF TRANSFER FUNCTIONS AT THE RIGHT HALF PLANE
Azeroğlu T.A.; Örnek B.N.; Düzenli T. (American Institute of Mathematical Sciences, 2022)In this paper, an inequality for a transfer function is obtained assuming that its residues at the poles located on the imaginary axis in the right half plane. In addition, the extremal function of the proposed inequality ...
