"This is a well-written and essentially self-contained survey on several applications of fixed-point theory. ... The book makes easy reading because the proofs are remarkably well structured. They are broken up into easily digestible parts and the claims are always clearly stated. There are five appendices which help to make the book almost self-contained." (Christian Fenske, zbMATH 1352.47002, 2017) "The chapters provide models for students to appreciate the art of a well-thought out seminar talk ... on a particular topic or theme. There are also a variety of exercises integrated into the lectures, 'to encourage active participation', which allow the text to be used for a course or an independent study. ... The book appears to be written to engage a young audience, yet there is more in it to provide pleasure to mathematicians further on in their career." (Tushar Das, Maa Reviews, maa.org, October, 2016)
