Complex Oscillation Theory of Differential Polynomials

Belaïdi, Benharrat; El Farissi, Abdallah (Acta Universitatis Palackianae Olomucensis. Facultas Rerum Naturalium. Mathematica, 2011)

In this paper, we investigate the relationship between small functions and differential polynomials gf (z) = d2f + d1f + d0f, where d0(z), d1(z), d2(z) are entire functions that are not all equal to zero with ρ(dj) ...
The frequency of the zeros of some differential polynomials

Belaïdi, Benharrat (Demonstratio Mathematica, 2013-03-01)

Let p(f) and p(f) denote respectively the iterated p-order and the iterated p-type of an entire function f. In this paper, we study the iterated order and the fixed points of some differential polynomials generated by ...
Growth and oscillation related to a second order linear differential equation

Belaϊdi, Benharrat (Mathematical Communications, 2013-05-10)

This paper is devoted to studying the growth and the oscillation of solutions of the second order non-homogeneous linear di erential equation f00 + A1 (z) eP(z)f0 + A0 (z) eQ(z)f = F; where P (z), Q(z) are nonconstant ...
Growth of solutions and oscillation of differential polynomials generated by some complex linear differential equations

Belaidi, Benharrat; El Farissi, Abdallah (Hokkaido Mathematical Journal, 2010)

This paper is devoted to studying the growth and the oscillation of solutions of the second order non-homogeneous linear differential equation f00 + A1(z)eP(z) f0 + A0(z)eQ(z) f = F; where P(z), Q(z) are nonconstant ...
Growth of solutions of higher order linear differential equations

Belaïdi, Benharrat; El Farissi, Abdallah (Mathematical Journal of Okayama University, 2014)

This paper is devoted to studying the growth of solutions of the higher order nonhomogeneous linear differential equation f (k)+ A k− 1 f (k− 1)+...+ A 2 f"+(D 1 (z)+ A 1 (z) e P (z)) f'+(D 0 (z)+ A 0 (z) e Q (z)) f= F (k≥ ...
On the growth of solutions of some higher order linear differential equations

Belaïdi, Benharrat; El Farissi, Abdallah (Applications of Mathematics, 2012-08-01)

n this paper we discuss the growth of solutions of the higher order nonhomogeneous linear differential equation f (k)+ Ak− 1f (k− 1)+...+ A2f′′+(D1 (z)+ A1 (z) eaz) f′+(D0 (z)+ A0 (z) ebz) f= F (k⩾ 2), where a, b are complex ...
SOME PROPERTIES OF FINITE ORDER SOLUTIONS OF A CLASS OF LINEAR DIFFERENTIAL EQUATIONS WITH ENTIRE COEFFICIENTS

Belaıdi, Benharrat; Hamouda, Saada (RAŢIU (RAŢĂ) MEFODIE TEODOR, 2013-07-01)

In this paper, we investigate the growth of solutions of some higher order linear differential equations. We find conditions on the coefficients which will guarantee the existence of an asymptotic value for a transcendental ...
