內容簡介

This book is an outgrowth of a course which I gave at Orsay duringthe academic year 1 966.67 MY purpose in those lectures was to pre-sent some of the required background and at the same time clarify theessential unity that exists between several related areas of analysis.These areas are：the existence and boundedness of singular integral op-erators；the boundary behavior of harmonic functions；and differentia-bility properties of functions of several variables.AS such the commoncore of these topics may be said to represent one of the central develop-ments in n.dimensional Fourier analysis during the last twenty years，and it can be expected to have equal influence in the future.These pos.

精彩書摘

The basic ideas of the theory of reaI variables are connected with theconcepts of sets and ftmctions，together with the processes of integrationand difirerentiation applied to them.WhiIe the essential aspects of theseideas were brought to light in the early part of our century，some of theirfurther applications were developed only more recently.It iS from thislatter perspective that we shall approach that part of the theory thatinterests US.In doing SO，we distinguish several main features： The theorem of Lebesgue about the differentiation of the integral.The study of properties related to this process iS best done in terms of a“maximal function”to which it gives rise：the basic features of the latterare expressed in terms of a“weak-type”inequality which iS characteristicof this situation. Certain covering lemmas.In general the idea iS to cover an arbitraryopen set in terms of a disioint union ofcubes or balls，chosen in a mannerdepending on the problem at hand.ORe such example iS a lemma ofWhitney，fTheorem 3）.Sometimes，however，it SHffices to cover only aportion of the set。as in the simple covering lemma，which iS used to provethe weak-type inequality mentioned above. f31 Behavior near a‘'general”point of an arbitrary set.The simplest notion here iS that of point of density.More refined properties are bestexpressed in terms of certain integrals first studied systematically by Marcinkiewicz.
（4）The splitting of functions into their large and small parts.Thisfeature which iS more of a technique than an end in itself，recurs often.ItiS especially useful in proving Linequalities，as in the first theorem ofthis chapter.That part of the proof of the first theorem iS systematizedin the Marcinkiewicz interpolation theorem discussed in§4 of this chapter and also in Appendix B.

本套叢書是數學大師給本科生們寫的分析學係列教材。第一作者E. M. Stein是一位調和分析大師，他是1999年沃爾夫奬獲得者，同時，他也是一位卓越的教師。他的學生，和學生的學生，加起來超過兩百多人，其中有兩位已經獲得瞭菲爾茲奬，2006年的菲爾茲奬獲奬者之一即為他的學生陶哲軒。這套教材在Princeton大學使用，同時其它學校，比如UCLA等名校也在本科生教學中使用。其教學目的是，用統一的、聯係的觀點來把現代分析的核心內容教給本科生們，力圖使本科生的分析學課程能接上現代數學研究的脈絡。

小學時，我每天上課需要經過一條石闆路，石闆路邊有一座石條砌成的房子，每到黃昏，胭脂一般的天色，敷在明晃晃的石闆路上，把整條巷子烘托得異常美好。也是每到這個時刻，就會聽到一個女人啜泣的聲音，淒淒婉婉，麯麯摺摺。也因此，那座房子在這所學校的學生裏，被講述成一個女鬼居住的地方。女鬼的名字就叫張美麗。
