Complex Oscillation of Solutions and Their Arbitrary-Order Derivatives of Linear Differential Equations With Analytic Coefficients of [p, q]-Order in the Unit Disc

Abstract

Throughout this article, we investigate the growth and fixed points of solutions of complex higher order linear differential equations in which the coefficients are analytic functions of [p, q]−order in the unit disc. This work improves some results of Belaïdi [3–5], which is a generalization of recent results from Chen et al. [9].
