The Growth and Zeros of Linear Differential Equations with Entire Coefficients of [p, q] - φ(r) Order.

In this paper, the authors investigate the growth and zeros of the solutions and the coefficients of higher order linear differential equations with entire coefficients of [p, q] - φ order, where p, q are positive integers and satisfy p ≥ q ≥ 1. The theorems that we obtain extend and improve many previous results. [ABSTRACT FROM AUTHOR]
