英文摘要: The numerical range of operators is a basic and important issue in the operator theory. In recent years, it has been found new applications in the field of quantum computing, so many experts pay attentions to it once again. This project focuses on the geometrical structure of the numerical range by means of operator block technique and fine analysis of spectral characteristics and researches the following questions about the numerical range: (1) Discuss some open problem about the numerical range, to give the answers or useful conclusions of two open problem. (2) Study the geometrical structure of operators numerical ranges, by the classification of the operator, the characteristics of various types of operators and means of the function calculus and the properties of the corner points, the boundary points and interior points and extend some conclusions of the finite-dimensional to infinite-dimensional space. (3) Explore the problems of numerical range from other areas, use the research results to these problems and find new way for numerical range from such applications.
