Weightd Composition Operatiors On Function Spaces And Analytic Function Randomization

The main content of this thesis is divided into two parts.First,we study the weighted composition operators from Besov space into the Zygmund type spaces on the unit disk.Second,This paper is divided into four chapters.Chapter 1 is the introduction.We briefly introduce the research significance and research status,and then introduce the main research content of this paper.In chapter 2,we give the necessary and sufficient conditions for the weighted composition operators to be bounded and compact operators from Besov space into the Zygmund type spaces,and then give the relevant proof.In chapter 3,the important results of the randomization of some function space functions are obtained,and the proof is given.In chapter 4,we summarize the thesis briefly.
