本书是作者多年来给普林斯顿大学本科一年级学生开设微积分的每周复习课。本书专注于讲述解题技巧,目的是帮助读者学习一元微积分的主要概念。深入处理一些基本内容,还复习一些主题。本书不仅可以作为参考书,也可以作为教材,定会成为任何一位需要微积分知识人学习一元微积分的非常好的指导书。
自从有了微积分,就有了微分表与积分表。有了具体的函数来求出其导数往往不是很困难,以致微分表常常不为人们所重视;而有了具体的函数来求其积分就不是这样了,有的也许可以容易地求出来,但大量的积分不是轻易求得出来的,于是积分表就一本一本不断地出版,从简单的到复杂的,在国外尤其是这样。由于自然科学和工程技术的不断发展,新的问题层出不穷,不断地提出各式各样的求积分的问题,于是过几年就会有新版的积分表出现,以供自然科学、工程技术和社会科学工作者使用。 我们参考了外尤其是国外一些新版的积分表和数学手册,如D.Zwillinger 主编的《Standard Mathematical Tableland Formulae》,J?J?图马和R.A?沃尔什主编的《工程数学手册》,I.S.Gradshteyn和I.M.Ryzhik主编的《Table of Integrals,Series,and Products》等,并广泛地征求了自然科学和工程
During the latter part of the seventeenth century the new mathe-matical analysis emerged as the dominating force in mathematics. It is characterized by the amazingly successful operation with infinite processes or limits. Two of these processes, differentiation and inte- gration, became the core of the systematic Differential and Integral Calculus, often simply called "Calculus,asic for all of analysis. The importance of the new discoveries and methods was immediately felt and caused profound intellectual excitement. Yet, to gain mastery of the powerful art appeared at first a formidable task, for the avail-able publications were scanty, unsystematic, and often lacking in clarity. Thus, it was fortunate indeed for mathematics and science in general that leaders in the new movement soon recognized the vital need for writing textbooks aimed at making the subject ac-cessible to a public much larger than the very small intellectual elite of the early days. One of the greatest mathematicians of modern time
This revision of the 1983 second edition of"Elliptic Partial Differential Equations of Second Order" corresponds to the Russian edition, published in 1989, in which we essentially updated the previous version to 1984. The additional text relates to the boundary H61der derivative estimates of Nikolai Krylov, which provided a fundamental ponent of the further development of the classical theory of elliptic (and parabolic), fully nonlinear equations in higher dimensions. In our presentation we adapted a simplification of Krylov's approach due to Luis Caffarelli.
Banach空间中的常微分方程理论是近二三十年发展起来的一个新的数学分支,它把常微分方程理论和泛函分析理论结合起来,利用泛函分析方法研究Banach空间中的常微分方程。它的理论在无穷常微分方程组、临界点理论、偏微分方程、不动点定理等多方面都有广泛的应用。特别是,临界点理论中常用的最速下降流线,即以是Banach空间常微分程方程理论作基础。由于它的重要性,又比较新,故被列为我国自然科学基金重点资助的项目之一。 在我国,研究Banach空间常微分方程理论的人很少,1985年,在第五届全国非线性泛函分析会议上,作者和孙经先副教授合作了《Banach空间中的常微分方程理论》综合报告,引起了许多人的兴趣。本书显然可作为综合性大学和高等师范大学有关专业的研究生教材,也可供有关教师和科技大工作者进行科研时参考。
