Inhaltsangabe:
- The purpose of this book is to lay out certain aspects of descriptive set theory. After initially establishing notation and generalities we proceed to the following topics: partitions, semirings, rings, $σ$-rings, $δ$-rings, products and sums, extension and generation. Extensive references and historical comments are included at the end of each section, as are further examples in the form of exercises and problems.
