AN IMPROVED LOWER BOUND FOR SCHWARZ LEMMA AT THE BOUNDARY
(KOREAN SOC MATHEMATICAL EDUCATION, 2016)
In this paper, a boundary version of the Schwarz lemma for the holomrophic function satisfying f (a) = b, vertical bar a vertical bar < 1, b is an element of C and Rf (z) > alpha, 0 <= alpha < vertical bar b vertical bar ...
INEQUALITIES FOR THE ANGULAR DERIVATIVES OF CERTAIN CLASSES OF HOLOMORPHIC FUNCTIONS IN THE UNIT DISC
(KOREAN MATHEMATICAL SOC, 2016)
In this paper, a boundary version of the Schwarz lemma is investigated. We take into consideration a function f (z) - z+c(p+1)z(p+1)+c(p+2)z(p+2)+... holomorphic in the unit disc and vertical bar f (z)/lambda f(z)+(1-lambda)z ...
ESTIMATES FOR A CERTAIN SUBCLASS OF HOLOMORPHIC FUNCTIONS
(KOREAN SOC MATHEMATICAL EDUCATION, 2019)
In this paper, a version of the boundary Schwarz Lemma for the holomorphic function belonging to N(alpha) is investigated. For the function f(z) = z + c(2)z(2) + c(3)z(3) + ... which is defined in the unit disc where f(z) ...
SOME RESULTS OF THE CARATHEODORY'S INEQUALITY AT THE BOUNDARY
(KOREAN MATHEMATICAL SOC, 2018)
In this paper, a boundary version of the Caratheodory's inequality is investigated. We shall give an estimate below vertical bar f' (b)vertical bar according to the first nonzero Taylor coefficient of about two zeros, ...
ESTIMATES FOR HOLOMORPHIC FUNCTIONS CONCERNED WITH JACK'S LEMMA
(PUBLICATIONS L INSTITUT MATHEMATIQUE MATEMATICKI, 2018)
We investigate a boundary version of the Schwarz lemma for classes H(alpha). Also, we estimate a modulus of the angular derivative of f(z) function at the boundary point b with f (b) = b/ (beta)root 2, 0 < beta <= 1. The ...
SOME RESULTS CONCERNED WITH HANKEL DETERMINANT FOR N (?) CLASS
(Korean Mathematical Soc, 2021)
In this paper, we give some results an upper bound of Hankel determinant of H2(1) for the classes of N (alpha). We get a sharp upper bound for H-2(1) = c(3)-c(2)(2) for N (alpha) by adding z(1), z(2), ... , z(n) zeros of ...
SOME RESULTS CONCERNED WITH HANKEL DETERMINANT
(Univ Kragujevac, Fac Science, 2023)
In this paper, we discuss different versions of the boundary Schwarz lemma and Hankel determinant for K (alpha) class. Also, for the function f(z) = z + c(2)z(2) + c(3)z(3) + center dot center dot center dot defined in the ...
