  • Growth and oscillation of differential polynomials in the unit disc. 
    Belaidi, Benharrat; El Farissi, Abdallah; Latreuch, Zinelaabidine (Electronic Journal of Differential Equations (EJDE)[electronic only], 2010)
    In this article, we give sufficiently conditions for the solutions and the differential polynomials generated by second-order differential equations to have the same properties of growth and oscillation. Also answer to the ...
  • Growth of solutions of linear differential equations in the unit disc 
    BELAÏDI, BENHARRAT (Bull. Math. Analy. Appl, 2011-03-01)
    In this paper, we investigate the growth of solutions of higher order linear differential equations with analytic coefficients in the unit disc∆={z∈ C:| z|< 1}. We obtain four results which are similar to those in the ...
  • Oscillation of fast growing solutions of linear differential equations in the unit disc 
    Belaıdi, Benharrat (Acta Univ. Sapientiae, Mathematica, 2010)
    In this paper, we investigate the relationship between solutions and their derivatives of the differential equation f (k) + A (z) f = 0, k ≥ 2, where A (z) 6≡ 0 is an analytic function with finite iterated porder and ...
