On The Regularity Of Solutions Of Differential Equations In Complex Field

In this thesis , we investigate the regularity of solutions of linear differential equations in complex field.In chapter 2, we study the regularity of solutions of some second order differential equations.In chapter 3, we study the regularity of solutions of higher order non -homogeneous differential equations where coefficients are rational functions or super entire functions.In chapter 4, we study the regularity of solutions of higher order homogeneous differential equations where coefficients are super meromorphic functions .In chapter 5, we study the oscillation of solutions of higher order linear differential equations where coefficients are regular super meromorphic functions .
