Some estimates for angular derivative at the boundary
(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
(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
(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 Associated with the Hyperbolic Sine Function
(Association of Mathematicians (MATDER), 2024)In this paper, we examine several characteristics of analytical functions related to the hyperbolic sine function and analyze the behavior of the hyperbolic sine function inside and at the boundary of the unit disk. © MatDer. -
SOME RESULTS ON JACK’S LEMMA FOR ANALYTIC FUNCTIONS
(Amasya Üniversitesi, 2022)In this paper, an upper bound will be found for the second coefficient in the Taylor expansion of the analytical function $p(z)$ using the Jack lemma. Also, the modulus of the angular derivative of the $I_{f}(z)=\frac{zp^{\prime ... -
SOME RESULTS ON THE SUBORDINATION PRINCIPLE FOR ANALYTIC FUNCTIONS
(Amasya Üniversitesi, 2022)The aim of this paper is to introduce the class of the analytic functions called and to investigate the various properties of the functions belonging this class. For the functions in this class, some inequalities related ...
