适用于物理学和数学的研究生，这本书介绍了弦论的简明和教学介绍。它的重点是解释弦论的关键概念，如玻色子弦、D膜、超对称性和超弦，并澄清粒子、场和弦之间的关系，而不假设粒子理论或量子场论的高级背景，使它能广泛地为各种背景的感兴趣读者所理解。从世界表（共形场论）和时空（有效场论）的角度分析了支撑当前研究的重要思想，如配分函数、紧化、规范对称性和T-对偶。无论是自学还是一学期的研究生课程，弦论简介都是学习弦论的学生必不可少的资源，其中包含示例和家庭作业问题，以培养理解力，并为教师提供完整的解决方案。
A Short Introduction to String Theory
Suitable for graduate students in physics and mathematics, this book presents a concise and pedagogical introduction to string theory. It focuses on explaining the key concepts of string theory, such as bosonic strings, D-branes, supersymmetry and superstrings, and on clarifying the relationship between particles, fields and strings, without assuming an advanced background in particle theory or quantum field theory, making it widely accessible to interested readers from a range of backgrounds. Important ideas underpinning current research, such as partition functions, compactification, gauge symmetries and T-duality are analysed both from the world-sheet (conformal field theory) and the space-time (effective field theory) perspective. Ideal for either self-study or a one semester graduate course, A Short Introduction to String Theory is an essential resource for students studying string theory, containing examples and homework problems to develop understanding, with fully worked solutions available to instructors.
