Title: Complex oscillation of entire solutions of
       higher-order linear differential equations

Author: Ting-Bin Cao (Shandong Univ., Jinan, China)
	 
Abstract: 
 In this paper, we investigate higher-order linear differential
 equations with entire coefficients of iterated order.
 We improve and extend a result of Belaidi and  Hamouda
 by using the estimates for the logarithmic derivative
 of a transcendental meromorphic function due to Gundersen and the
 Winman-Valiron theory. We also consider the nonhomogeneous linear
 differential equations by using  the basic method  and some
 lemmas from the present and other three authors.
