Explores Euclidean groups, the Lorentz and Poincaré groups, and discrete symmetries like space inversion and time reversal.
You can access or view the book through the following reputable digital libraries and repositories:
The text systematically builds the machinery of group theory from scratch. It assumes a familiarity with linear algebra and basic quantum mechanics, guiding the reader through several critical domains: 1. Basic Group Concepts and Core Definitions Wu-ki Tung Group Theory In Physics Pdf

: The book is praised for keeping intermediate steps visible, making it highly suitable for self-study. Key Topics and Structure Explores Euclidean groups, the Lorentz and Poincaré groups,
: You can find detailed descriptions and chapter breakdowns on platforms like Google Books or Perlego .
: The main text prioritizes the physical consequences and applications of theorems, while the more rigorous mathematical proofs are often deferred to detailed appendices to keep the book self-contained. Basic Group Concepts and Core Definitions | Chapter
