The unique characteristic of this book is that it considers the theory of partial differential equations in mathematical physics as the language of continuous processes， that is to say， as an interdisciplinary science that treats the hierarchy of mathematical phenomena as reflections of their physical counterparts. Special attention is drawn to tracing the development of these mathematical phenomena in different natural sciences， with examples drawn from continuum mechanics， electrodynamics， transport phenomena， thermodynamics， and chemical kinetics. At the same time， the authors trace the interrelation between the different types of problems elliptic， parabolic， and hyperbolic - as the mathematical counterparts of stationary and evolutionary processes. This interrelation is traced through study of the asymptotics of the solutions of the respective initial boundaryvalue problems both with respect to time and the governing parameters of the problem. This combination of mathematical comprehensiveness and natural scientific motivation represents a step forward in the presentation of the classical theory of PDEs， one that will be appreciated by both graduate students and researchers alike.本书为英文版。

In 1901 Adolf Hurwitz published a short note showing that Fourier series can be used to prove the isoperimetric inequality for domains in the Euclidean plane，and in a subsequent article he showed how spherical harmonics can be utilized to prove an analogous inequality for three-dimensional convex bodies. A few years later Hermann Minkowski used spherical harmonics to prove an interesting characterization of （three-dimensional） convex bodies of constant width. The work of Hurwitz and Minkowski has convincingly shown that a study of this interplay of analysis and geometry， in particular of Fourier series and spherical harmonics on the one hand， and the theory of convex bodies on the other hand， can lead to interesting geometric results. Since then many articles have appeared that explored the possibilities of such methods.本书为英文版。

This book is based on one-semester courses given at Harvard in 1984， at Brown in 1985， and at Harvard in 1988. It is intended to be， as the title suggests， a first introduction to the subject. Even so， a few words are in order about the purposes of the book. Algebraic geometry has developed tremendously over the last century. During the 19th century， the subject was practiced on a relatively concrete， down-to-earth level; the main objects of study were projective varieties， and the techniques for the most part were grounded in geometric constructions. This approach flourished during the middle of the century and reached its culmination in the work of the Italian school around the end of the 19th and the beginning of the 20th centuries.Ultimately， the subject was pushed beyond the limits of its foundations： by the end of its period the Italian school had progressed to the point where the language and techniques of the subject could no longer serve to express or carry out the ideas of its best practitioners.本书为英文版。

以李群无限维表示理论的观点来研究自守形式理论是目前数论、代数、调和分析和几何学等学科交汇点上的一门新兴活跃的数学领域，它并且将是数学进展的一个重要方向。本书深入浅出地对Langlands的这个理论的基本内容进行了系统的阐述。全书共分六章参主要内容包括在代数数域上的2×2矩阵群在无限维的Hilbert空间上的表示与自守形式，Eisenstein级。数的解析延拓和函数方程，以及迹公式的证明。本书采用的观点和论证的方法都是尽可能从较为初等的角度采引导读者进入这个领域。因此，本书给准备进入这个数学新领域从事研究工作的读者提供了一本最佳的入门救科书。 本书可作为高等学校数学专业研究生课教材，也可供高等学校数学专业师生，以及数学工作者参考。

“我有一种跟滕菲、谭平一道学在德国的感觉。到处走走，听听，看看，新的观念便在不经意中走近我。文章这样写法也很好，不但是读起来容易，而且，它留给我们想象与推理的空间也很大。读过这篇文章，我得到不少的启迪，它将我的比较杂乱的及不甚连贯的有关教学方面的思考串联起来，因此，我说它很有价值。编辑这一套书，恰逢其时——我深切感到我们的学院教学的改革势在必行。却捡食着几乎被他们忘却了的东西。文章中说到观念的建立，我们可以清楚地感到技术应当选定的位置。我们是否太过重视技术选择而忽视了中国绘画中不乏的观念？还有，关于美的定义，不也很值得我们比照吗？我们真的很需要知道别人在想什么，做什么。知道的目的也是为了能使别人对我们之所想、所做感兴趣。”
