“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)
