    • Best bound for λ- pseudo starlike functions 

      KRİSHNA, D. Vamshee; SHALİNİ, D. (Ankara Üniversitesi Fen Fakültesi, 2019-02-01)
      In this paper, we obtain sharp upper bound to the second Hankel determinant for the functions belong to the class of λ- pseudo starlike functions, an interesting sub class of univalent functions defined in the open unit ...
    • Coefficient estimates for bi-concave functions 

      Sakar, F. Müge; Güney, H. Özlem (Ankara Üniversitesi, 2019-02-01)
      In this study,a new class C_{Σ}^{p,q}(α) of analytic and bi-concave functions were presented in the open unit disc. The coefficients estimates on the first two Taylor-Maclaurin coefficients |a₂| and |a₃| were found for ...
