    • A combinatorial discussion on finite dimensional Leavitt path algebras 

      Koç, Ayten; Esin, Songül; Güloğlu, İsmail; Kanuni, Müge (Hacettepe Univ, Fac Sci, Hacettepe Univ, Fac Sci, Beytepe, Ankara 06800, Turkey, 2014)
      Any finite dimensional semisimple algebra A over a field K is isomorphic to a direct sum of finite dimensional full matrix rings over suitable division rings. We shall consider the direct sum of finite dimensional full ...
    • 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 = ...
    • q-Harmonic mappings for which analytic part is q-convex functions of complex order 

      Çetinkaya, Asena; Polatoğlu, Yaşar (Hacettepe Univ, Fac Sci, Hacettepe Univ, Fac Sci, Beytepe, Ankara 06800, Turkey, 2018)
      We introduce a new class of harmonic function f, that is subclass of planar harmonic mapping associated with q-difference operator. Let h and g are analytic functions in the open unit disc D = {z : vertical bar z vertical ...
    • Some properties of q- close-to-convex functions 

      Uçar, H. Esra Ozkan; Mert, Oya (Hacettepe Univ, Fac Sci, Hacettepe Univ, Fac Sci, Beytepe, Ankara 06800, Turkey, 2017-12)
      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 ...
