USDThe theory of causal fermion systems represents a novel approach to fundamental physics and is a promising candidate for a unified physical theory. This book offers a comprehensive overview of the theory, structured in four parts: the first lays the necessary mathematical and physical foundations; the second offers an introduction to the theory and the causal action principle; the third describes the mathematical tools for analyzing causal fermion systems; and the fourth gives an outlook on the key physical applications. With relevance across mathematical and theoretical physics, the book is aimed at graduate students and researchers interested in novel approaches to the structure of spacetime and alternative perspectives to the more established quantum field theories. It can be used for advanced courses in the subject or as a reference for research and self-guided study. Exercises are included at the end of each chapter to build and develop key concepts.
- As the first comprehensive text on causal fermion systems, the book is an essential resource for anyone with an interest in novel approaches to fundamental physics
- Covers the foundational mathematical and physical aspects in detail to ensure the book is accessible to as broad an audience as possible
- Well suited as a companion to self-guided study and as a framework for courses in the subject, with exercises included in each chapter to support learning
