  • Differential polynomials generated by second order linear differential equations 
    Belaïdi, Benharrat; El Farissi, Abdallah (Journal of Applied Analysis, 2008)
    In this paper, we study fixed points of solutions of the differential equation f+ A1 (z) f+ A0 (z) f= 0, where Aj (z)(≡ 0)(j= 0, 1) are transcendental meromorphic functions with finite order. Instead of looking at the zeros ...
  • 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 and Zeros of Meromorphic Solutions to Second-Order Linear Differential Equations 
    Belaidi, Benharrat; Andasmas, Maamar (International Journal of Analysis and Applications, 2016-04-20)
    The main purpose of this article is to investigate the growth of meromorphic solutions to homogeneous and non-homogeneous second order linear differential equations f00+ Af0+ Bf= F, where A (z), B (z) and F (z) are meromorphic ...
  • Nonexistence of subnormal solutions for a class of higher order complex differential equations 
    Belaïdi, Benharrat; Zemirni, Mohamed Amine (Bulletin of the Transilvania University of Brasov. Mathematics, Informatics, Physics. Series III, 2015-07-01)
    In this article, we investigate the existence of subnormal solutions for a class of higher order complex di erential equations. We generalize the result of N. Li and L. Z. Yang [14], L. P. Xiao [17] and also result of ...
  • On the hyper order of solutions of a class of higher order linear differential equations 
    Belaïdi, Benharrat; ABBAS, Saıd (An. f-ftiinj. Univ." Ovidius" Constanta Ser. Mat, 2008-01-01)
    In this paper, we investigate the order and the hyper order of entire solutions of the higher order linear differential equation f(k) +Ak−1 (z) e Pk−1(z) f(k−1)+...+A1 (z) e P1(z) f +A0 (z) e P0(z) f =0 (k ≥ ...
