Abstract

The singular values of a compact operator A are by definition the eigenvalues of (A*A) 1/2. These numbers are important characteristics for compact operators. In this chapter the main properties of the singular values are studied. In the last sectionthe trace class operators are introduced. For the latter operators the trace and determinant will be defined in the next chapter.
