Rezensionen

"The chapters are relatively independent. For this reason, this would be a nice book to hand to an advanced undergraduate or a beginning graduate student to supplement coursework or to find a topic for a project. ... Overall, the author succeeds in providing an intriguing collection of theorems beyond those widely known from basic study." (Michele Intermont, MAA Reviews, September 15, 2019)
"This monograph is written by a well-known expert in fixed point theory and presents his choice of results from this wide area of research. ... The monograph can serve as a very useful introduction into the fixed point topic, which is one of the most applicable parts, both of Topology and Nonlinear Analysis." (Zoran Kadelburg, zbMath 1412.54001, 2019)
