This paper is devoted to Ceshro operators and composition operators on holomorphic function spaces of Cn.It consists of four chapters.In Chapter 1,the background and present conditions are introduced and summarized for the study of boundedness and compactness of Cesà ro operators and composition operators,and we line the main results of the paper as follows.In Chapter 2,let g1,g2 be normal functions.For all 0<p,q<∞,the necessary and sufficient conditions are given for the Cesà ro operator Tψ:Ag1p→Ag2q being bounded or compact on Bergman type spaces.In Chapter 3,the boundness and compactness of Cesà ro operator Tg from F(q) space to Bloch type space on the unit ball of Cn for q>-n-1,α>0 are studied and the necessary and sufficient conditions are given for the Ceshro operator Tg.In Chapter 4,the equivalences of some compactness conditions for composition opreator between Bloch spaces on the polydisc of Cn are studied.At the same time, the best simple expressions are obtained.
