    • A certain class of harmonic mappings related to functions of bounded radius rotation 

      Kahramaner, Yasemin; Polatoğlu, Yaşar; Yemişçi Şen, Arzu (2018)
      Let R-k be the class of functions with bounded radius rotation and let S-H be the class of sense-preserving harmonic mappings. In the present paper we investigate a certain class of harmonic mappings related to the function ...
    • Application of the subordination principle to the multivalent harmonic mappings with shear construction method 

      Polatoğlu, Yaşar; Yavuz Duman, Emel; Özkan, H. Esra (2011-06)
      The harmonic function in the open unit disc D = (z is an element of C vertical bar z vertical bar < 1} can be written as a sum of an analytic and an anti-analytic function. f = h(z) + g(z), where h(z) and g(z) are analytic ...
    • Q-Starlike Functions of Order Alpha 

      Polatoğlu, Yaşar; Uçar, Faruk; Yılmaz, Bülent (TURKIC WORLD MATHEMATICAL SOC, 2018)
      For all q is an element of (0, 1) and 0 <= alpha < 1 we define a class of analytic functions, so-called q-starlike functions of order alpha on the open unit disc D = {z : vertical bar z vertical bar < 1}. We will study ...
