    • NEW ESTIMATES FOR MEROMORPHIC FUNCTIONS 

      Ornek, Bulent Nafi (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 ...
    • RESULTS ASSOCIATED WITH THE SCHWARZ LEMMA ON THE BOUNDARY 

      Ornek, Bulent Nafi (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 ...
    • 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 ...
