Non-homogeneous Linear Differential Equations with Solutions of Finite Order

In this paper we investigate the growth of finite order solutions of the differential equation f ((k)) + A (k-1)(z) f ((k-1)) + center dot center dot center dot + A(1)(z) f' + A(0)(z) f = F (z), where A(0)(z); center dot center dot center dot ; A (k-1)(z) and F (z) not equivalent to 0 are entire functions. We find conditions on the coefficients which will guarantees the existence of an asymptotic value for a transcendental entire solution of finite order and its derivatives. We also estimate the lower bounds of order of solutions if one of the coefficient is dominant in the sense that has larger order than any other coefficients.
