"This is an excellent introductory text on measure theory and integration, with a very good presentation of two fundamental aspects of functional analysis: Hilbert spaces and Banach spaces. The material is presented at a level accessible for a graduate student in mathematics or a researcher in another, related discipline. ... Each section contains a large number of examples and exercises accompanied by generous hints." (Victoria R. Steblovskaya, Mathematical Reviews, June, 2016) "This book, written by leading experts, is a well-crafted textbook covering a medley of relevant topics in measure theory and functional analysis in a rather get-to-the-point-quickly fashion, yet resulting in a very readable and enjoyable journey. ... The book manages to cover quite a lot of ground in a relatively short number of pages strewn with plenty of exercises. ... All-in-all, the student reading this book stands to gain much knowledge, develop and hone her skills, and enjoy the trip." (Ittay Weiss, MAA Reviews, maa.org, April, 2016)
