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.

　　为什么思维中要对客观对象进行分析呢?我们知道，自然界中的任何事物都不是单纯的和不可分的，而是具有复杂的构成。它们总是由不同的部分、方面、因素和层次组成的。果核可以剖开，化合物可以分解，所谓“元素”、“原子”和“基本粒子”也都不是单纯的，都有其一定的结构。客观事物构成的复杂性决定着思维分析的必要性。没有分折，人们对事物只能有个浑沌的认识。

最近京东搞活动买的，比其它网站便宜一点，有些书在我所在的这个地区就没货 所以发货就晚了。但是书真的不错 只要发货就很快就到，应该是正品，快递很快哦 继续努力，书直接给我送到楼下，这样的服务态度真的值得其他的快递员学习，东京快递真的不错。上周周六，闲来无事，上午上了一个上午网，想起好久没买书了，一段时间不逛书店就周身不爽，于是上京东挑选了一大批书。
