Solutions of Non-Homogenous Linear Differential Equations

This article is devoted to the study of solutions of non-homogenous linear differential equations having entire coefficients. We get all non-trivial solutions of infinite order of equation $f^{(n)}+a_{n-1}(z)f^{(n-1)}+\dots +a_1{f}^{\mathrm{\prime }}+a_{0}f=H(z)$, by restricting the conditions on coefficients.
