Firstly, we give some technologies and notations, and introduce the definitions of numerical range , convex set, extreme point, maximal partial isometry etc. Subsequently we give some well-known theorems such as the Krein-Milman theorem, polar decomposition theorem and spectral theorem.
首先我们介绍了一些符号的表示意义，接着引入了数值域，凸集，凸集端点，极大部分等距等概念，而后给出一些广泛熟知的定理如Krein-Milman定理，极分解定理，谱定理等。
