內容簡介

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.

凸分析的書。從中我們可以大緻瞭解到一些凸優化的概念，比如凸集，凸函數，凸優化問題，綫性規劃，二次規劃，二次約束二次規劃，半正定規劃等，從而對凸優化問題有個初步的認識。

　　為什麼思維中要對客觀對象進行分析呢?我們知道，自然界中的任何事物都不是單純的和不可分的，而是具有復雜的構成。它們總是由不同的部分、方麵、因素和層次組成的。果核可以剖開，化閤物可以分解，所謂“元素”、“原子”和“基本粒子”也都不是單純的，都有其一定的結構。客觀事物構成的復雜性決定著思維分析的必要性。沒有分摺，人們對事物隻能有個渾沌的認識。

好書，經典

想說說書的裝訂和印刷問題。拿到的書最後幾頁竟然有很多小孔，難道是被蟲蛀瞭？

最近京東搞活動買的，比其它網站便宜一點，有些書在我所在的這個地區就沒貨 所以發貨就晚瞭。但是書真的不錯 隻要發貨就很快就到，應該是正品，快遞很快哦 繼續努力，書直接給我送到樓下，這樣的服務態度真的值得其他的快遞員學習，東京快遞真的不錯。上周周六，閑來無事，上午上瞭一個上午網，想起好久沒買書瞭，一段時間不逛書店就周身不爽，於是上京東挑選瞭一大批書。
