... where A i (z) are analytic in the unit disc ∆ = {z : |z| < 1}, i = 0, 1, ..., k − 1, k ≥ 2. For the properties of solutions of Eq (1.1), including growth, zero distribution and function space properties, many results have been obtained, for example [9,10,14,16,20,22,23,25] and therein references. In addition, the differential equations have wide applications in various science discipline, for example engineering, predator-prey equations, population growth and decay, Newton's law of cooling and so on, see [1,5,24,28,29] and therein references. ...

... The general problem of Ozawa has been proposed by Heittokangas, and given by Gundersen, see [10,Section 5]. More and more papers focus on the existence of finite order solutions of second linear differential equations (1.3) with entire coefficients, even precise form of finite order solutions, see [14,15,17,24,36,39]. ...
