Notes on Real Analysis and Measure Theory: Fine Properties of Real Sets and Functions

by Alexander Kharazishvili

Overview

This monograph gives the reader an up-to-date account of the fine properties of real-valued functions and measures. The unifying theme of the book is the notion of nonmeasurability, from which one gets a full understanding of the structure of the subsets of the real line and the maps between them. The material covered in this book will be of interest to a wide audience of mathematicians, particularly to those working in the realm of real analysis, general topology, and probability theory. Set theorists interested in the foundations of real analysis will find a detailed discussion about the relationship between certain properties of the real numbers and the ZFC axioms, Martin's axiom, and the continuum hypothesis.

Editorial Reviews

This monograph deals with classical topics of real analysis and measure theory which show a number of interesting phenomena. … This makes the presented material useful and inspiring. … Every chapter is finished with a solid portion of exercises … of various difficulty. More advanced exercises are enriched with hints and comments.” (Marek Balcerzak, Mathematical Reviews, June, 2023)

“The text is mostly self-contained and at the end of each chapter are exercises providing additional information to the presented topic. It makes the book accessible to graduate and post-graduate students.” (Jaroslav Tišer, zbMATH 1504.26003, 2023)
