本书作者采取了与许多教材以紧李群的表示论作为理论基础不同的安排，并精心挑选一系列材料，以给予读者更广阔的视野。为介绍紧李群，本书涵盖了 Peter-weyl定理、极大环面的共轭性（提供了两组证明），Weyl特征标公式等内容。随后本书研究了复分析群，一般非紧李群，内容包括：Weyl 群的Coxeter表示、Iwasawa及Bruhat分解、Cartan分解、对称空间、Cayley变换、相对根系、Satake图形，扩展的 Dyakin图以及李群嵌入的方式综述。本书通过介绍表示论在多种领域中的应用（这些领域有：随机矩阵论、Toeplitz矩阵的子式、对称代数分解、 Gelfand对、Hecke代数、有限一般线性群的表示及Grassmann簇与旗簇的上同调），并将对称群的表示论与酋群间的Frobenius- Schur对偶作为统一的主题处理，使读者能够对表示理论有更加深刻地理解。
