内容简介

　　In this book we aim to present， in a unified framework， a broad spectrum of mathematical theory that has grown in connection with the study of problems of optimization， equilibrium， control， and stability of linear and nonlinear systems. The title Variational Analysis refiects this breadth.
　　For a long time， variational problems have been identified mostly with the 'calculus of variations'. In that venerable subject， built around the minimization of integral functionals， constraints were relatively simple and much of the focus was on infinite-dimensional function spaces. A major theme was the exploration of variations around a point， within the bounds imposed by the constraints， in order to help characterize solutions and portray them in terms of 'variational principles'. Notions of perturbation， approximation and even generalized differentiability were extensively investigated， Variational theory progressed also to the study of so-called stationary points， critical points， and other indications of singularity that a point might have relative to its neighbors， especially in association with existence theorems for differential equations.

书内容是好，里面对subdifferential刻画详细无出其右。但是世图能不能长点心？每次翻开这本书我得带个防毒面具吗？印刷质量已经不能用烂来形容了。简直是危害健康啊！~上打印的都比你质量好

　　不可否认，美国人学工程及数学的人确实越来越少，学商及法律的人也越来越多，但这并不意味着一个普通的（average）受过教育的美国人的数学水平要低于一个普通的受过教育的中国人。即使是在美国的商学院、法学院里数学好的学生肯定也是美国人。这是因为美国的中学提倡的是通才教育，高中的数学是有一定标准的，并且数学中强调逻辑与推理的训练。而中国的学生初中毕业就开始文理分科，其结果是美国最烂的高中毕业的学生的数学水平也要比中国最好的大学毕业的文科博士高很多。美国的正规学校，初中以前基本放羊，但一到高中，立刻严谨。美国一个正规高中学生受到的学业压力不比中国孩子轻。一个普通的中国人在他（她）受教育的过程中，只有在初中以前，有可能有机会比美国人数学好。
