    • Harmonic mappings for which second dilatation is Janowski functions 

      Yavuz Duman, Emel; Polatoğlu, Yaşar; Kahramaner, Yasemin; Darus, Maslina (2013)
      In the present paper we extend the fundamental property that if h(z) and g(z) are regular functions in the open unit disc D with the properties h(0) = g(0) = 0, h maps D onto many-sheeted region which is starlike with ...
    • On generalized Janowski starlike logharmonic 

      Mohd, Maisarah Haji; Darus, Maslina; Polatoğlu, Yaşar; Yavuz Duman, Emel (2011)
      In this paper, we consider univalent logharmonic mappings of the form f(z) = zh(z)g(z) defined on the open unit disc with the normalization condition g(0) = 1 and h(0) 6= 0. We investigate the class of generalized ...
    • On some alpha-convex functions 

      Owa, Shigeyoshi; Polatoğlu, Yaşar; Yavuz, Emel; Acu, Mugur; Al-Oboudi, Fatima; Darus, Maslina (2008-06)
      In this paper, we define a general class of α-convex functions, denoted by MLβ,α(q), with respect to a convex domain D (q(z) ∈ Hu(U), q(0) = 1 , q(U) = D) contained in the right half plane by using the linear operator ...
