    • An investigation of the certain class of multivalent harmonic mappings 

      Polatoğlu, Yaşar; Özkan Uçar, Hatice Esra; Aydoğan, Seher Melike (2016)
      The main purpose of the present paper is to investigate some properties of the certain class of sense-preserving p-valent harmonic mappings in the open unit disc D = {z is an element of C parallel to z vertical bar < 1}.
    • Bounded Log-Harmonic Functions with Positive Real Part 

      Özkan Uçar, Hatice Esra; Polatoğlu, Yaşar (Academic Press inc Elsevier Science, 525 B St, Ste 1900, San Diego, Ca 92101-4495 USA, 2013-03-01)
      Let H(D) be the linear space of all analytic functions defined on the open unit disc D = {z vertical bar vertical bar z vertical bar < 1}, and let B be the set of all functions w(z) is an element of H(D) such that vertical ...

    • Some properties of q- close-to-convex functions 

      Özkan Uçar, Hatice Esra; Mert, Oya; Polatoğlu, Yaşar (2017)
      Quantum calculus had been used first time by M.E.H.Ismail, E.Merkes and D.Steyr in the theory of univalent functions [5]. In this present paper we examine the subclass of univalent functions which is defined by quantum ...
    • The radius of starlikeness p-Valently analytic functions in the unit disc 

      Polatoğlu, Yaşar; Bolcal, Metin; Yemişci, Halime Arzu; Özkan Uçar, Hatice Esra (TUBİTAK, 2006)
      In the present paper we shall give the radius of starlikeness for the classes of p-valent analytic functions in the unit disc D = {z | |z| < 1 } .
