Abstract.
In this paper, we investigate the relationship
between solutions and their derivatives of the differential equation
f ^{(k)} + A(z) f = 0, k ³ 2,
where A(z) is a transcendental meromorphic function withρ _{p}(A) = ρ > 0 and meromorphic functions of finite iterated p-order.
Keywords:
Linear differential equations; Meromorphic
solutions; Iterated order; Iterated exponent of convergence of the sequence
of distinct zeros.
