Ultimately, this short monograph will be of interest as a quick guide to researchers who need a notation reference, well organized overview of the literature, or an introduction to the subject, looking for connection with their own field; also for graduate students who are looking for a bird's eye view or need help with determining the learning path. It must be added that students especially will appreciate that the authors provide solutions to the exercises. (Tomasz Artur Stachowiak, Mathematical Reviews, December, 2019)
The book represents a very useful tool for graduate students and beginning researchers in a large area of the theory and applications of the Dirac equation. It can be useful for all the stages of learning: from the initial acknowledgement to deep investigations. ... The book will be very useful to everybody desiring to make an economy with special articles from various journals. (Alex B. Gaina, zbMath 1416.81003, 2019)
