    • A certain class of starlike log-harmonic mappings 

      Aydoğan, Melike; Polatoğlu, Yaşar (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2014-11)
      In this paper we investigate some properties of log-harmonic starlike mappings. For this aim we use the subordination principle or Lindelof Principle (Lewandowski (1961) [71). (C) 2014 Elsevier B.V. All rights reserved.
    • Janowski Starlike Log-Harmonic Univalent Functions 

      Polatoğlu, Yaşar; Deniz, Erhan (Hacettepe Univ, Fac Sci, Hacettepe Univ, Fac Sci, Beytepe, Ankara 06800, Turkey, 2009-04)
      Let h(z) and g(z) be analytic functions in the open unit disc D = {z vertical bar vertical bar z vertical bar < 1}, with the normalization h(0) = g((0))under bar> = 1. The class of log-harmonic mappings of the form f = ...
    • Some radius problem for certain families of analytic functions 

      Polatoğlu, Yaşar; Bolcal, Metin (TÜBİTAK, 2000)
      The aim of this paper is to give bounds of the radius of α-convexity for certain families of analytic functions in the unit disc. The radius of α-convexity is generalization of the radius of convexity and the radius of ...
