Growth of solutions of complex differential equations with coefficients of finite iterated order.
The aim of this paper is to consider the following three problems:i (1) for a given uniformly q-separated sequence satisfying certain conditions, find a coefficient function A(z) analytic in the unit disc such that f”’ + A(z)f = 0 possesses a solution having zeros precisely at the points of this sequence; (2) find necessary and sufficient conditions for the differential equation (*) in the unit disc to be Blaschke-oscillatory; (3) find sufficient conditions on the analytic coefficients of the...
In this paper we discuss the growth of solutions of the higher order nonhomogeneous linear differential equation where , are complex constants that satisfy and
