A course on Borel sets. (English) Zbl 0903.28001
Graduate Texts in Mathematics. 180. New York, NY: Springer. xvi, 261 p. (1998).
This is a very clearly written book concerning an introduction to the classical theory of Borel sets and measurable selections. The book is divided onto five chapters that contain: Chapter 1 – set theoretic preliminaries (ordinal and cardinal numbers, alephs, trees and the Souslin operation); Chapter 2 – topological preliminaries (Polish spaces, the Baire space $$N^N$$, the Cantor space $$2^N$$, and some theorems that help in transforming many problems from general Polish spaces to the Baire space or to the Cantor space); Chapter 3 – the hierarchy and properties of Borel sets (universal sets, reduction and separation theorems); Chapter 4 – basic properties of analytic and coanalytic sets; Chapter 5 – most of the major measurable selection and uniformization theorems that are important for applications. The book contains also a large number of interesting excercises.
