Growth of meromorphic solutions of finite logarithmic order of linear difference equations

Belaïdi B.

Fasciculi Mathematici

2015

Nr 54

5--20

In this paper, we deal with the growth and the oscillation of solutions of the linear difference equation an (z) f (z + n) + an-1 (z) f (z + n - 1) + ··· + a1 (z) f (z + 1) + a0 (z) f (z) = 0, where an(z), ···, a0(z) are meromorphic functions of finite logarithmic order such that an(z)a0(z) ≠0.

The frequency of the zeros of some differential polynomials

Belaïdi B.

Demonstratio Mathematica

2013

Vol. 46, nr 1

75--86

Let ρp(ƒ) and σp(ƒ) denote respectively the iterated p-order and the iterated p-type of an entire function ƒ. In this paper, we study the iterated order and the fixed points of some differential polynomials generated by solutions of the differential equation f''+A1(z)f'+A0(z)f=0 where A1(z), A0(z) are entire functions of finite iterated p-order such that ρp(A1) = ρp(A0) = ρ(0< ρ <+∞) and σp(A1)< σp(A0) =σ(0< σ <+∞).
