Abstract

In this paper, we investigate the complex oscillation of the differential equation

$$f^{\left( k \right)} + A_{k - 1} f^{\left( {k - 1} \right)} + \cdots + A_0 f = F$$

whereA k−1, …,A 0, F # 0 are finite order transcendental entire functions, such that there exists anA d(0≤d≤k−1) being dominant in the sense that either it has larger order than any otherA j(j=0.…,d−1, d+1.…, k−1), or it is the only transcendental function We obtain some precise estimates of the exponent of convergence of the zero-sequence of solutions to the above equation.
