An Application of Schwarz Lemma for Analytic Functions in the Unit Disc
(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
(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 ... -
Applications of the Jack's lemma for the meromorphic functions
(Springernature, 2021)In this paper, we give some results on zf'(z)/f(z) for the certain classes of f(z) meromorphic functions. For the function f(z) = 1/z + c(0) + c(1)z + c(2)z(2)+ ... defined in the punctured disc U = {z : 0 -
Boundary Schwarz Lemma for Holomorphic Functions
(UNIV NIS, FAC SCI MATH, 2017)In this paper, a boundary version of Schwarz lemma is investigated. We take into consideration a function f (z) holomorphic in the unit disc and f (0) = 0 such that vertical bar R-f vertical bar < 1 for vertical bar z ... -
Estimates Concerned with Hankel Determinant for M (?) Class
(Univ Nis, Fac Sci Math, 2022)In this paper, we give an upper bound of Hankel determinant of (H2(1)) for the classes of M (alpha), alpha is an element of C. Also, for M (alpha), we obtain a sharp estimate for the classical Fekete-Szego center dot ... -
ESTIMATES FOR ANALYTIC FUNCTIONS ASSOCIATED WITH SCHWARZ LEMMA ON THE BOUNDARY
(Kangwon-Kyungki Mathematical Soc, 2022)In this paper, we will introduce the class of analytic functions called R (alpha, lambda) and explore the different 5properties of the functions belonging to this class. -
ON BOUNDS FOR THE DERIVATIVE OF ANALYTIC FUNCTIONS AT THE BOUNDARY
(Kangwon-Kyungki Mathematical Soc, 2021)In this paper, we obtain a new boundary version of the Schwarz lemma for analytic function. We give sharp upper bounds for vertical bar f'(0)vertical bar and sharp lower bounds for vertical bar f'(c)vertical bar with c is ... -
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 ... -
