Abstract


In this paper, we investigate the order of growth of transcendental meromorphic
solutions of the linear dierential equation

$f^{(k)}+\sum_{j=0}^{k-1} hj(z) e^{Pj(z) } f^{(j)}=F$


where k>=2 is an integer, Pj (z) (j = 0,...,k-1) are nonconstant polynomials, hj (z) (j =0; :::; k 􀀀 1) and F (≠0) are meromorphic functions. Under some conditions, we prove that every transcendental meromorphic solution of the above equation is of infinite order.
