Title: Looking for / Sharing: Group Theory in Physics – Wu-Ki Tung (PDF)

Post:

Hi everyone,

I'm currently studying the applications of group theory in quantum mechanics and particle physics, and one text that keeps coming up as a classic is "Group Theory in Physics" by Wu-Ki Tung (World Scientific, 1985).

Unlike many pure math treatments, Tung's book is highly regarded for its physics-first approach — covering finite groups, Lie groups, and their representations with clear connections to angular momentum, particle classification, and scattering theory. It sits nicely between the rigor of Hamermesh and the more applied style of Georgi.

If anyone has a PDF copy they're willing to share, I'd greatly appreciate it. Alternatively, if you've worked through this book, I'd love to hear:

  • How it compares to Tinkham or Cornwell for self-study
  • Whether the problem sets are worth doing in full
  • If the later chapters (e.g., on Lorentz and Poincaré groups) still hold up well today

Happy to exchange notes or problem solutions with others currently going through the text.

Thanks in advance!

Final Verdict

If your goal is to understand the Standard Model, General Relativity, or Supersymmetry, you cannot avoid Lie Groups. Wu-Ki Tung’s Group Theory in Physics remains the definitive bridge between the abstract mathematics of Lie Algebras and the concrete reality of particle physics.

It is dense, but it is a treasure trove of insight. If you are stuck on Wigner rotations or the classification of relativistic particles, this is the book that will unstuck you.

Have you used Wu-Ki Tung's book in your studies? Do you prefer it to Georgi or Hamermesh? Let us know in the comments.

Wu-Ki Tung’s Group Theory in Physics is widely considered the "modern Wigner," serving as the bridge between abstract algebra and the actual work physicists do. If you are looking for the PDF, you are likely a graduate student or a serious self-learner trying to decode the symmetries of the universe. The Core Philosophy: Intuition Before Rigor

Unlike many math-heavy textbooks that start with dense axioms, Tung’s approach is pedagogical. He often moves from intuition to generalization. For instance, he introduces isomorphisms before homomorphisms because they are easier to visualize, and he uses illustrative examples to motivate a topic before diving into the formal theory.

Decoding the Universe: Why Wu-Ki Tung’s Group Theory is Still a Physics Must-Read

In the world of theoretical physics, some textbooks are mere references, while others are "rites of passage." Wu-Ki Tung’s Group Theory in Physics

falls firmly into the latter category. First published in 1985, this book remains a cornerstone for graduate students and researchers trying to bridge the gap between abstract algebra and the actual mechanics of the universe. What Makes This Book Special?

Many group theory books are written by mathematicians for mathematicians, leaving physicists drowning in "formal rigor" without seeing how it applies to a quantum state. Tung takes a different path. Pedagogy First

: Unlike texts that start with the most general case, Tung often starts with intuition—like isomorphism before homomorphism—because it’s easier to visualize. The "Missing Link" Content

: It covers the "middle ground" that introductory books skip but advanced ones expect you to know, such as Wigner’s classification Wigner–Eckart theorem Young tableaux Self-Contained Appendices

: To keep the main text readable, the heavy technical proofs and linear vector space summaries are tucked away in extensive appendices. Key Topics Explored

Tung’s structure is designed to build your "symmetry toolkit" from the ground up: Representations of Groups : The core of how we describe physical states. Continuous Groups (SO(3) and SU(2))

: Essential for understanding rotations and spin in quantum mechanics. Lorentz and Poincaré Groups

: The mathematical backbone of special relativity and relativistic field theory. Space-Time Inversions

: Deep dives into parity (P) and time reversal (T) invariance. Is It for You? Group Theory in Physics 9971966565, 9971966573

Wu-Ki Tung's " Group Theory in Physics " is widely regarded as one of the most accessible yet rigorous textbooks for graduate students and advanced undergraduates attempting to master symmetry principles in quantum and classical systems.

First published by World Scientific in 1985, this book fills a unique gap in physics education. It covers the advanced material that many introductory books skip, but that high-level quantum field theory and particle physics texts assume you already know. 📘 Why This Book Stands Out

Exceptional Pedagogy: Tung prioritizes clarity of main ideas and physical consequences without sacrificing mathematical integrity.

No "Hand-Waving": Unlike many standard physics texts that treat group theory loosely, Tung provides formal proofs and relies heavily on precise linear algebra. Introduction Group theory is a branch of mathematics

Strategic Appendices: To keep the main text readable and flowing smoothly, Tung places the heavy, technical mathematical proofs in the appendices.

Bridging the Gap: Reviewers frequently note that it sits perfectly between ultra-abstract math books and overly simplified chemistry point-group books. 🗺️ Core Topics Covered

The text takes readers on a sequential journey from basic finite group definitions up through the complex Lie groups that govern modern particle physics. 1. Finite Groups and Representations

The book starts with the basics: group axioms, subgroups, classes, and cosets. It quickly moves into representation theory, Schur's Lemma, and the Great Orthogonality Theorem, which are foundational for quantum mechanics. 2. Rotations and Angular Momentum (

A major chunk of the book is dedicated to continuous groups. Tung masterfully handles the double-covering of the rotation group , clearing up exactly why fermions have half-integer spin. 3. Advanced Tools for Physicists

This is where Tung's book proves its weight in gold. He explicitly breaks down:

The Wigner-Eckart Theorem: The mathematical backbone behind calculating quantum transition rates and selection rules.

Young Tableaux: A visual, combinatoric method used to reduce direct products of representations, heavily used in the quark model. 4. The Lorentz and Poincaré Groups

For students transitioning into Relativistic Quantum Mechanics and Quantum Field Theory, chapters on the Lorentz group and Poincaré group are absolutely vital. Tung teaches how to classify physical particles according to their mass and spin (Wigner's Classification). 🛑 Limitations to Keep in Mind

While the book is highly praised, prospective readers should be aware of a few aspects:

Heavy Notation: Tung uses rigorous, explicit index notation. While mathematically bulletproof, it can sometimes make formulas look more intimidating than they actually are.

Dated Applications: Because it was published in 1985, you will not find discussions on modern developments like supersymmetry, string theory, or topological insulators.

Dry Tone: The book is structured like a traditional math-physics textbook. If you prefer a more conversational, intuitive approach with less index-heavy math, a book like A. Zee's "Group Theory in a Nutshell for Physicists" on Princeton University Press might be a better fit. 💻 About the "Pdf" and Physical Copies If you are looking for a copy of the book: Group Theory in Physics 9971966565, 9971966573
