内容简介

convexity has been increasingly important in recent years in the study of extremum problems in many areas of applied mathematics. the purpose of this book is to provide an exposition of the theory of convex sets and functions in which applications to extremum problems play the central role.
systems of inequalities， the minimum or maximum of a convex function over a convex set， lagrange multipliers， and minimax theorems are among the topics treated， as well as basic results about the structure of convex sets and the continuity and differentiability of convex functions and saddle-functions. duality is emphasized throughout， particularly in the form of fenchers conjugacy correspondence for convex functions.

分析就是将研究对象的整体分为各个部分、方面、因素和层次，并分别地加以考察的认识活动。比如说，我们研究植物细胞，将它分为细胞壁，细胞膜、细胞质和细胞核几个不同部分来认识，并分别地考察各部分所特有的性质和功能，由此就可知，一个细胞外面包着一层透明的薄壁，这就是细胞壁，它有保护和支持作用；紧贴在细胞壁里面的一层很薄的膜，就是细胞膜，它控制着物质的出入，既不让有用的物质任意流出细胞，也不让有害的物质轻易地进入细胞，细胞膜里面包着的透明物质就是细胞质，细胞质里含有很多非常重要的物体，如植物绿色部分的细胞质里，含有制造有机养料的叶绿体，细胞质里还含有—个或几个象水泡似的液泡，细胞液含有糖分或带有酸味的物质；细胞质里还含有一个近似球形的细胞核，细胞核里含有在遗传上起着重大作用的物质。我们分别对植物细胞的各部分作如上的考察，这样的认识活动就是分析。
