On the complex oscillation of higher order linear differential equations

Kai Liu and Lian-Zhong Yang

Shandong University

Abstract

In this paper, we investigate the growth of solutions and the existence of subnormal solutions for a class of higher order linear differential equations. We obtain some results which improve and extend the results of Chen-Shon [2] and Gundersen-Steinbart [5].

Keywords: periodic differential equation, subnormal solution, e-type order
