超弦和M理論是現代物理學中最有趣最活躍的研究課題之一。該問題比較困難同時也充滿爭議，一些人稱之為“終極理論”，這是因為超弦理論有可能解決困擾人們多年的難題，即統一二十世紀最偉大的兩個理論：廣義相對論和量子場論。
《超弦和M理論導論(第2版)》全面細緻地講解超弦理論和該領域的最新研究進展，內容包括四維超弦，Kac-Moody代數，Teichmuller空間和Calabi-Yau流形，M理論和D膜，對偶和BPS關係，矩陣模型等，可以作為研究生教材，同時對研究人員也有參考價值。作者首先簡要介紹了點粒子理論，然後利用費曼路徑積分詳細討論超弦理論。超弦研究需要很多數學工具，書中分別作了介紹，如指標定理，同調論和Kahler流形等。在第二版中，作者對內容做了整體修訂，並添加了M理論的三個新章節。閱讀《超弦和M理論導論(第2版)》需要量子力學和相對論的基本知識。
讀者對象：理論物理、高能物理、場論和絃論等專業的高年級本科生、研究生和相關專業的科研人員。
