“The structure of the chapters can make the reader independent, thus the book can be used ‘outside of the classroom’ for self-teaching by both young researchers and experienced scholars. The book is well written … . it is ready to fill a gap in the literature for such an interesting and active branch of mathematics.” (Dimitrios Varsos, zbMATH 1426.20001, 2020)
