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