Properties of solutions of complex differential equations in the unit disc

Abstract

In this paper, we investigate the growth and oscillation of higher order di erential polynomial with meromorphic coe cients in the unit disc = fz : jzj < 1g generated by solutions of the linear di erential equation f(k) + A(z) f = 0 (k 2) ; where A(z) is a meromorphic function of nite iterated p-order in :
