On The Growth Of Solutions Of Some Classes Of Complex Difference-differential Equations

We investigate the growth of solutions of several kinds of difference-differential equations and systems of difference-differential equations in this thesis,several results are obtained.This thesis include three chap-ters.The relevant knowledge of Nevanlinna theory is recalled,and the progress of solutions of complex differential equations and complex dif-ference equations and complex difference-differential equations are intro-duced in the Chapter 1.The growth of solutions of two kinds of complex difference-differential equations is studied by using Nevanlinna theory,which extend previous results by^[5]in the Chapter 2.The growth of solutions of two kinds of systems of complex difference-differential equations is studied by using Nevanlinna theory,which is improvement of previous results by^[40]in the Chapter 3.
