商品描述
In this classic text for advanced undergraduates and graduate students of physics, author Günter Scharf carefully analyzes the role of causality in quantum electrodynamics. His approach offers full proofs and detailed calculations of scattering processes in a mathematically rigorous manner. This third edition contains Scharf's revisions and corrections plus a brief new Epilogue on gauge invariance of quantum electrodynamics to all orders.
The book begins with Dirac's theory, followed by the quantum theory of free fields and causal perturbation theory, a powerful method that avoids ultraviolet divergences and solves the infrared problem by means of the adiabatic limit. Successive chapters explore properties of the S-matrix — such as renormalizability, gauge invariance, and unitarity — the renormalization group, and interactive fields. Additional topics include electromagnetic couplings and the extension of the methods to non-abelian gauge theories. Each chapter is supplemented with problems, and four appendixes conclude the text.

商品描述(中文翻譯)
在這本經典的高年級本科生和研究生物理學教材中，作者Günter Scharf仔細分析了因果性在量子電動力學中的角色。他的研究方法提供了完整的證明和詳細的散射過程計算，以數學上嚴謹的方式進行。本書的第三版包含了Scharf的修訂和更正，以及關於量子電動力學的規範不變性的新簡短後記，涵蓋所有階數。
本書以狄拉克（Dirac）的理論開始，接著介紹自由場的量子理論和因果擾動理論，這是一種強大的方法，可以避免紫外發散並通過絕熱極限解決紅外問題。隨後的章節探討了S-矩陣的性質——如重正化性、規範不變性和單位性——重正化群以及互動場。其他主題包括電磁耦合及其方法擴展到非阿貝爾規範理論。每章都附有習題，並以四個附錄結束本書。
