Except for minor modifications, this monograph represents the lecture notes of a course I gave at UCLA during the winter and spring quarters of 1991. My purpose in the course was to present the necessary background material and to show how ideas from the theory of Fourier integral operators can be useful for studying basic topics in classical analysis, such as oscillatory integrals and maximal functions. The link between the theory of Fourier integral operators and classical analysis is of course not new, since one of the early goals of microlocal analysis was to provide variable coefficient versions of the Fourier transform. However, the primary goal of this subject was to develop tools for the study of partial differential equations and, to some extent, only recently have many classical analysts realized its utility in their subject.
李殿璞编著的这本《非线性控制系统理论基础( 第2版)》讲授非线性系统理论。非线性系统理论与线性系统理论相平行、相对应,但更具一般性。非线性系统理论所使用的主要数学工具微分几何方法已被证明是分析和设计非线性系统的卓有成效的和强有力的工具。本书便于教学使用,内容由浅入深,概念清晰,理论严谨,有重新构建的更为合理的体系结构,侧重于系统地介绍基础理论,同时也兼顾实际应用。为使读者时刻掌握学习的主动性和更便于自学使用,本书除在每章节前对内容作概括介绍外,还对每个定理、命题、例题都给出方法提示或目标指示。
随着科学技术的发展,在自然科学和社会科学领域中广泛存在的非线性问题,越来越引起人们的关注,而且许多非线性问题的研究最终可归结为非线性偏微分方程来描述,通过对非线性偏微分方程的求解和定性分析来研究。 《临沂博士教授文库:非线性偏微分方程的解析解》给出了微分几何中的AC=BD模式,并利用吴微分特征列法,给出某些定理的机械化证明。 给出了一般形式的Riccati方程多种形式的解,进而提出了求非线性偏微分方程孤波解的机械化方法,此方法可以将非线性微分方程的求解转化为非线性超定代数方程组的求解,从而建立了吴方法与微分方程求解之间的桥梁。
This is primarily a textbook on mathematical analysis forgraduate students in economics. While there are a large number ofexcellent textbooks on thiroad topic in the mathematicsliterature, most ofthese texts are overly advanced relative to theneeds of the vast majority of economics students and concentrate onvarious topics that are not readily helpful for studying economictheory. Moreover, it seems that most economics students lack thetime or courage to enroll in a math course at the graduatelevel. Sometimes this is not even for bad reasons, for only fewmath departments offer classes that are designed for the parhcularneeds of economists. Unfortunately,more often than not, theconsequent lack ofmathematical background cre-ates problems for thestudents at a later stage of their education, since an exceedinglylarge fraction ofeconomic theory is imperable without somerigorouackground in real analysis. The present text aims atproviding a remedy for this inconvenient situation.

A carefully prepared account of thebasic ideas in Fourier analysis and its applications to the studyof partial differential equations. The author succeeds to make hisexposition accessible to readers with a limited background, forexample, those not acquainted with the Lebesgue integral. Readersshould be familiar with calculus, linear algebra, and plexnumbers. At the same time, the author has managed to includediscussions of more advanced topics such as the Gibbs phenomenon,distributions, Sturm-Liouville theory, Cesaro summability andmulti-dimensional Fourier analysis, topics which one usually doesnot find in books at this level. A variety of worked examples andexercises will help the readers to apply their newly acquiredknowledge.
