    • 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 ...
    • Some remarks for certain subclasses of meromorphic 1 ? valent functions 

      Örnek B.N. (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 ...
