The Complex Oscillation Properties Of The Solutions Of Some Types Of Differential Equations With Entire Coefficients

Content: In this thesis,we investigate some properties of the solutions of linear differential equations.In chapter 2,we study the order of growth and the hyper-order of solutions of a class of higher order linear differential equation,and get exact estimation of the order of growth of the solutions in 3 theorems.In chapter 3,we introduce the iterated i-order convergence exponent of the sequence of fixed points of meromorphic function f(z),and investigate the fixed point and iterated order of solutions of linear differential equations,with entire coefficients fo infinite order.We obtain some properties and results.
