Growth of solutions of second order linear differential equations

This paper is devoted to studying the growth of solutions of equations of type f + h(z)eazf + Q(z)f = H(z) where h(z), Q(z) and H(z) are entire functions of order at most one. We prove four theorems of such type, improving previous results due to Gundersen and Chen. © 2007 Elsevier Inc. All rights reserved
