摘要
We investigate the [p, q]-order of growth of solutions of the following complex linear differential equation f((k)) + A(k-1)(z) f((k-1)) + ... + A(1)(z)f' + A(0)(z)f = 0, where A(j)(z) are analytic in (C) over bar - {z(0)}, z(0) is an element of C. Some estimations of [p, q]-order of growth of solutions of the equation are obtained, which is generalization of previous results from Fettouch-Hamouda.
