BEHAVIOR OF HOLOMORPHIC FUNCTIONS ON THE BOUNDARY OF THE UNIT DISC
(KOREAN SOC MATHEMATICAL EDUCATION, 2017)
In this paper, we establish lower estimates for the modulus of the non tangential derivative of the holomorphic function f (z) at the boundary of the unit disc. Also, we shall give an estimate below vertical bar f ''(b)vertical ...
RESULTS ASSOCIATED WITH THE SCHWARZ LEMMA ON THE BOUNDARY
(Korean Mathematical Soc, 2023)
In this paper, some estimations will be given for the analytic functions belonging to the class R (& alpha;). In these estimations, an upper bound and a lower bound will be determined for the first coefficient of the ...
NEW ESTIMATES FOR MEROMORPHIC FUNCTIONS
(Publications L Institut Mathematique Matematicki, 2021)
A boundary version of the Schwarz lemma for meromorphic functions is investigated. For the function I-n f(z) = 1/z + Sigma(infinity)(k=2) k(n)c(k-2)z(k-2), belonging to the class of W, we estimate from below the modulus ...
Sharpened Forms for ?-Spirallike Function of Complex Order on the Boundary
(Amer Inst Physics, 2021)
We present a different version of Schwarz Lemma and estimate the angular derivative of the function zf'(z)/f(z) from below for lambda-spirallike function f(z) of complex order at the boundary of the unit disc D by taking ...
