1. Convex sets and functions have many interesting and useful properties which are not explored in detail here.
   凸集和凸函数具有很多重要的和有用的性质，在此不作详细讨论。
2. Duality is emphasized throughout,particularly in the form of Fenchel's conjugacy correspondence for convex functions.
   这本书的目的是为了提供各类凸集和凸函数理论的介绍，它们在极值问题的应用中发挥核心作用。
