Bibliographical and Historical Comments
One gets a strange feeling having seen the same drawings as if drawn by the same hand in the works of four schol- ars that worked completely independently of each other. An involuntary thought comes that such a striking, myste- rious activity of mankind, lasting several thousand years, cannot be occasional and must have a certain goal. Having acknowledged this, we come by necessity to the question: what is this goal? I.R. Shafarevich. On some tendencies of the develop- ment of mathematics.
However, also in my contacts with the American Shake- speare scholars I confined myself to the concrete problems of my research: dating, identification of prototypes, direc- tions of certain allusions. I avoided touching the problem of personality of the Great Bard, the “Shakespeare prob- lem”; neither did I hear those scholars discussing such a problem between themselves. I.M. Gililov. A play about William Shakespeare or the Mystery of the Great Phoenix.
The extensive bibliography in this book covers, however, only a small portion of the existing immense literature on measure theory; in particular, many authors are represented by a minimal number of their most character- istic works. Guided by the proposed brief comments and this incomplete list, the reader, with help of modern electronic data-bases, can considerably en- large the bibliography. The list of books is more complete (although it cannot pretend to be absolutely complete). For the reader’s convenience, the bibli- ography includes the collected (or selected) works of A.D. Alexandrov [15], R. Baire [47], S. Banach [56], E. Borel [114], C. Carath´eodory [166], A. Den- joy [215], M. Fr´echet [321], G. Fubini [333], H. Hahn [401], F. Haus- dorff [415], S. Kakutani [482], A.N. Kolmogorov [535], Ch.-J. de la Vall´ee Poussin [575], H. Lebesgue [594], N.N. Lusin [637], E. Marczewski [652], J. von Neumann [711], J. Radon [780], F. Riesz [808], V.A. Rohlin [817], W. Sierpi´nski [881], L. Tonelli [956], G. Vitali [990], N. Wiener [1017], and G. &W. Young [1027], where one can find most of their cited works along with other papers related to measure theory. Many works in the bibliography 410 Bibliographical and Historical Comments are only cited in the main text in connection with concrete results (including exercises and hints). Some principal results are accompanied by detailed com- ments; in many other cases we mention only the final works, which should be consulted concerning the previous publications or the history of the question. Dozens of partial results mentioned in the book have an extremely interesting history, revealed through the reading of old journals, the exposition of which I had to omit with regret. Most of the works in the bibliography are in English and French; a rel- atively small part of them (in particular, some old classical works) are in German, Russian, and Italian. For most of the Russian works (excepting a limited number of works from the 1930s–60s), translations are indicated. The reader is warned that in such cases, the titles and author names are given according to the translation even when versions more adequate and closer to the original are possible. Apart from the list of references, I tried to be consistent in the spelling of such names as Prohorov, Rohlin, Skorohod, and Tychonoff, which admit different versions. The letter “h” in such names is responsible for the same sound as in “Hardy” or “Halmos”, but in different epochs was transcribed differently, depending on to which foreign language (French, German, or English) the translation was made. Nowadays in official documents it is customary to represent this “h” in the Russian family names as “kh” (although, it seems, just “h” would be enough). Now several remarks are in order on books on Lebesgue measure and in- tegration. The first systematic account of the theory was given by Lebesgue himself in the first edition of his lectures [582] in 1904. In 1907, the first edition of the fundamental textbook by Hobson [436] was published, where certain elements of Lebesgue’s theory were included (in later editions the cor- responding material was considerably reworked and enlarged); next the books by de la Vall´ee Poussin [572] (note that in later editions the Lebesgue integral is not considered) and [574] and Carath´eodory [164] appeared. It is worth noting that customarily the form La Vall´ee Poussin de is used for the alpha- betic ordering; however, in some libraries this author is to be found under “V” or “P”, see Burkill [149]. These four books are frequently cited in many works of the first half of the 20th century. Let us also mention an extensive treatise Pierpont [756]. Some elements of Lebesgue’s measure theory were discussed in Hausdorff [412] (in later editions this material was excluded). Some back- ground was given in Sch¨onflies[858]. Elements of Lebesgue’s measure theory were considered in the book Nekrasov [709] published in 1907. Early surveys of Lebesgue’s theory were La Vall´eePoussin [573], Bliss [95], Hildebrandt [432], and a series of articles Borel, Zoretti, Montel, Fr´echet [115], published in the Encyclopedie des sciences math´ematiques (the reworked German ver- sion was edited by Rosenthal [823]). It is worth mentioning that in Lusin’s classical monograph [633], the first edition of which was published in 1915 and was his magister dissertation (by a special decision of the scientific committee, the degree of Doctor was conferred on Lusin in recognition of the outstanding level of his dissertation), the fundamentals of Lebesgue’s theory were assumed Bibliographical and Historical Comments 411 to be known (references were given to the books by Lebesgue and de la Vall´ee Poussin). The subject of Lusin’s dissertation was the study of fine properties of the integral (not only the Lebesgue one, but also more general ones), the primitives and trigonometric series. Another very interesting document is the magister dissertation of G.M. Fichtenholz [288] (the author of the excellent calculus course [295]) completed in February 1918. Unfortunately, due to the well-known circumstances of the time, this remarkable handwritten man- uscript was never published and was not available to the broad readership.1 Fichtenholz’s dissertation is a true masterpiece, and many of its results, still not widely known, retain an obvious interest. The manuscript contains 326 pages (the title page is posted on the website of the St.-Petersburg Mathe- matical Society; the library of the Department of Mechanics and Mathematics of Moscow State University has a copy of the dissertation). The introduction (pp. 1–58) gives a concise course on Lebesgue’s integration. The principal original results of G.M. Fichtenholz are concerned with limit theorems for the integral and are commented on in appropriate places below (see also Bogachev [106]). The dissertation contains an extensive bibliography (177 titles) and a lot of comments (in addition to historical notes, there are many interesting remarks on mistakes or gaps in many classical works). In the 1920s the following books appeared: Hahn [398], Kamke [485], van Os [731], Schlesinger, Plessner [853], Townsend [963]. Vitali’s books [988], [989] also contain large material on Lebesgue’s integration. In 1933, the first French edition of the classical book Saks [840] was published (the second edition was published in English in 1937); this book still remains one of the most influential reference texts in the subject. The same year was marked by publication of Kolmogorov’s celebrated monograph [532], which built math- ematical probability theory on the basis of abstract measure theory. This short book (of a booklet size), belonging to the most cited scientific works of the 20th century, strongly influenced modern measure theory and became one of the reasons for its growing popularity. Also in the 1930s, the textbooks by Titchmarsh [947], Haupt, Aumann [411] (the first edition), and Kestel- man [504] were published. Fundamentals of Lebesgue measure and integra- tion were given in Alexandroff, Kolmogorov [17]. The basic results of measure theory were presented in the book Tornier [961] on foundations of probability theory, which very closely followed Kolmogorov’s approach (a drawback of Tornier’s book is a complete omission of indications to the authorship of the presented theorems). In addition, in those years there existed lecture notes published later (e.g., von Neumann [710], Vitali, Sansone [991]). Note also the book Stone [914] containing material on the theory of integration. In 1941 the excellent book Natanson [706] was published (I.P. Natanson was Fichtenholz’s student and his book was obviously influenced by the aforemen- tioned dissertation of Fichtenholz). In McShane [668], the presentation of the

Lodkin for their generous help. 412 Bibliographical and Historical Comments theory of the integral is based on the Daniell approach, and then a standard course is given including a chapter on the Lebesgue–Stieltjes integral. Jessen’s book [465] was composed of a series of journal expositions published in the period 1934–1947. Let us also mention Cramer’s book [190] on mathematical statistics where a solid exposition of measure and integration was included. It should be noted that Kolmogorov’s concept of foundations of probability theory lead to a deep penetration of the apparatus of general measure theory also into mathematical statistics, which is witnessed not only by Cramer’s book, but also by many subsequent expositions of the theoretical foundations of mathematical statistics, see Barra [62], Lehmann [600], Schmetterer [854]. After World War II the number of books on measure theory consider- ably increased because this subject became part of the university curriculum. Below we give a reasonably complete list of such books. A very thorough pre- sentation of measure theory and integration was given in Smirnov [891], the first edition of which was published in 1947. In 1950, Natanson’s book [707] (which was a revised and enlarged version of the already-cited book [706]) appeared. This excellent course has become one of the most widely cited textbooks of real analysis. In addition to the standard material it offers a good deal of special topics not found in other sources. Also in 1950, Halmos’s classical book [404] was published; since then it has become a standard refer- ence in the subject. Three other popular textbooks from the 1950s are Riesz, Sz.-Nagy [809], Munroe [705], and Kolmogorov, Fomin [536]. In my opinion, the book by Kolmogorov and Fomin (it was translated in many languages and had many revised and reprinted editions) is one of the best texts on the the- ory of functions and functional analysis for university students. It grew from the lecture notes [533] on the course “Analysis-III” initiated in 1946 at the Moscow State University by Kolmogorov (he was the first lecturer; among the subsequent lecturers of the course were Fomin, Gelfand, and Shilov). At the time Kolmogorov was planning to write a book on measure theory (the pro- jected book was even mentioned in the bibliography in [363],whereonp.19 “the reader is referred to that book for any explanations related to measure theory and the Lebesgue integral”). See also Kolmogorov [534]. However, the Halmos book was published, and Kolmogorov gave up his idea, saying, as witnessed by Yu.V. Prohorov, that “there is no desire to write worse than Halmos and no time to write better”. By the way, for a similar reason, the book by Marczewski announced in 1947 in Colloq. Math., v. 1, was never completed. Along with these classics of measure theory, one should mention the outstanding treatise of Doob [231] on stochastic processes, which became another triumph of applications of general measure theory (it is worth not- ing that Doob was the scientific advisor of Halmos; see also Bingham [92]). Two years later, in 1955, Lo`eve’s textbook [617] on probability theory was published; this book, a standard reference in probability theory, contains an excellent course on measure and integration. Also in the 1950s, Bourbaki’s treatise [119] on measure theory appears in several issues. Certainly not suit- able as a textbook and, in addition, rather chaotically written, Bourbaki’s Bibliographical and Historical Comments 413 book offered the reader a lot of useful (and not available from other sources) information in various directions of abstract measure theory. A dozen other books on measure and integration published in the 1950s can be found in the list below. Finally, the famous monograph Dunford, Schwartz [256] must be mentioned. Being the most complete encyclopedia of functional analysis, it also presents in depth and detail large portions of measure theory. For the next 50 years the measure-theoretic literature has grown tremendously and it is hardly possible to mention all textbooks and monographs published in many countries and in many languages (e.g., the Russian edition of this book mentions several dozen Russian textbooks). This theory is usually pre- sented in books under the corresponding title as well as under the titles “Real analysis”, “Abstract analysis”, “Analysis III”, as part of functional analysis, probability theory, etc. The following list contains only the books in English, French and German with a few exceptions in Russian, Italian and Spanish (without repeating the already-cited books) that I found in the libraries of several dozen largest universities and mathematical institutes over the world (typically, every particular library possesses considerably less than a half of this list): Adams, Guillemin [1], Akilov, Makarov, Havin [6], Aliprantis, Burkin- shaw [18], Alt [20], Amann, Escher [21], Anger, Bauer [25], Arnaudies [38], Art´emiadis [39], Ash [41], [42], Asplund, Bungart [43], Aumann [44], Au- mann, Haupt [45], Barner, Flohr [61], de Barra [63], Bartle [64], Bass [68], Basu [69], Bauer [70], Bear [72], Behrends [73], Belkner, Brehmer [74], Bel- lach, Franken, Warmuth, Warmuth [75], Benedetto [76], Berberian [78], [79], Berezansky, Sheftel, Us [80], Bichteler [87], [88], Billingsley [90], Boccara [101], [102], Borovkov [118], Bouziad, Calbrix [122], Brehmer [124], Bri- ane, Pag`es [128], Bruckner, Bruckner, Thomson [136], Buchwalter [139], Burk [146], Burkill [148], Burrill [150], Burrill, Knudsen [151], Cafiero [158], Capi´nski, Kopp [161], Carothers [169], Chae [171], Chandrasekharan [172], Cheney [175], Choquet [178], Chow, Teicher [179], Cohn [184], Constan- tinescu, Filter, Weber [186], Constantinescu, Weber [187], Cotlar, Cignoli [188], Courr`ege [189], Craven [191], Deheuvels [209], DePree, Swartz [218], Denkowski, Mig´orski, Papageorgiou [216], Descombes [219], DiBenedetto [221], Dieudonn´e[225], Dixmier [229], Doob [232], Dorogovtsev [234], Dsha- lalow [239], Dudley [251], Durrett [257], D’yachenko, Ulyanov [258], Edgar [260], Eisen [267], Elstrodt [268], Federer [282], Fernandez [283], Fichera [284], Filter, Weber [297], Floret [301], Folland [302], Fonda [304], Foran [305], Fremlin [327], Fristedt, Gray [329], Galambos [335], G¨anssler,Stute [337], Garnir [344], Garnir, De Wilde, Schmets [345], Gaughan [347], Genet [350], Gikhman, Skorokhod [353] (1st ed.), Gleason [361], Goffman [366], Goffman, Pedrick [367], Goldberg [370], Gouyon [375], Gramain [377], Gra- uert, Lieb [378], Graves [380], G¨unzler [384], Gut [385], de Guzm´an,Ru- bio [388], Haaser, Sullivan [389], Hackenbroch [391], Hartman, Mikusi´nski [410], Haupt, Aumann, Pauc [411], Hennequin, Tortrat [421], Henstock 414 Bibliographical and Historical Comments

Chapters or sections on Lebesgue integration and related concepts (mea- sure, measurable functions) are also found in many calculus (or mathematical analysis) textbooks, e.g., see Amerio [23], Beals [71], Browder [133], Fleming [300], Forster [306], Godement [365], Heuser [430], Hille [434], Holdgr¨un [441], James [454], Jost [473], K¨onigsberger [540], Lee [598], Malik, Arora [645], Pugh [774], Rudin [834], Sprecher [901], Tricomi [964], Walter [1004], Vitali [988], or in introductory expositions of the theory of functions, e.g., Bridges [129], Brudno [137], Kripke [549], Lusin [636], Oxtoby [733], Rey Pastor [792], Richard [793], Saxe [846], Saxena, Shah [847]. Various interest- ing examples related to measure theory are considered in Gelbaum, Olmsted [349], Wise, Hall [1022]. One could extend this list by adding lecture notes from many university libraries as well as books in all other languages in which Bibliographical and Historical Comments 415 mathematical literature is published (e.g., Hungarian, Polish, and other East- European languages, the languages of some former USSR republics, Chinese, Japanese, etc.). Moreover, our list does not include books (of advanced na- ture) that contain extensive chapters on measure theory (such as Meyer [686] and others cited in this text on diverse occasions), but do not offer the back- ground material on integration. See also a series of surveys in Pap [738]. The listed books cover (or almost cover) standard graduate courses, but, certainly, considerably differ in many other respects such as depth and com- pleteness and the principles of presentation. Some (e.g., [251], [268], [327], [431], [440], [452], [788], [829], [962], [1043]), give a very solid exposition of many themes, others emphasize certain specific directions. I give no clas- sification of the type “textbook or monograph” because in many cases it is difficult to establish a border line, but it is obvious that some of these books cannot be recommended as textbooks for students and some of them have now only a historical interest. On the other hand, even a quick glance at such books is very useful for teaching, since it helps to see the well-known from yet another side, provides new exercises etc. In particular, the acquaintance with those books definitely influenced the exposition in this book. Many books on the list include extensive collections of exercises, but, in addition, there are books of problems and exercises that are entirely or partly devoted to measure and integration (some of them develop large portions of the theory in form of exercises): Aliprantis, Burkinshaw [19], Ansel, Ducel [27], Arino, Delode, Genet [37], Benoist, Salinier [77], Bouys- sel [121], Capi´nski, Zastawniak [162], Dorogovtsev [233], Gelbaum [348], George [351], Kaczor, Nowak [475], Kirillov, Gvishiani [519], Kudryavtsev, Kutasov, Chekhov, Shabunin [553], Laamri [562], Leont’eva, Panferov, Serov [604], Letac [605], Makarov, Goluzina, Lodkin, Podkorytov [644], Ochan [725], [727], Telyakovski˘ı[939], Ulyanov, Bahvalov, D’yachenko, Kazaryan, Cifuentes [968], Wagschal [1003]. There one can find a lot of simple ex- ercises, which are relatively not so numerous in this book. At present the theory of measure and integration (or parts of this theory) is given in courses on real analysis, measure and integration or is included in courses on func- tional analysis, abstract analysis, and probability theory. In recent years at the Department of Mechanics and Mathematics of the Lomonosov Moscow University there has been a one-semester course “Real analysis” in the second year of studies (approximately 28 lecture hours and the same amount of time for exercises). The curriculum of the author’s course is given in the Appen- dix below. In addition, several related questions are studied in the course on functional analysis in the third year. Many books cited above give bibliographical and historical comments; we especially note Anger, Portenier [26], Benedetto [76], Cafiero [158], Chae [171], Dudley [251], Dunford, Schwartz [256], Elstrodt [268], Hahn, Rosen- thal [402], McDonald, Weiss [666], Rosenthal [823]. Biographies of the best- known mathematicians and recollections about them can be found in their collected works and in journal articles related to memorial dates; see also 416 Bibliographical and Historical Comments
Bingham [91], Bogoljubov [109], Demidov, Levshin [210], Menchoff [681], Paul [740], Phillips [750], Polischuk [763], Szymanski [929], Taylor [935], Taylor, Dugac [936], Tumakov [965], and the book [683]. In 1988, 232 let- ters from Lebesgue to Borel spanning about 20 years were discovered (Borel’s part of the correspondence was not found); they are published in [595] with detailed comments (this typewritten work is available in the library of Univer- sit´eParis–VI in Paris; large extracts are published in several issues of the more accessible journal Revue des math´ematiquesde l’enseignement sup´erieur,and 111 letters are published in [596]). Lebesgue’s letters, written in a very lively style, reflect many interesting features of the scientific and university life of the time (which will still be familiar to scholars today), the ways of develop- ment of analysis of the 20th century, and the personal relations of Lebesgue with other mathematicians. The history of the development of the theory of measure and integration at the end of the 19th century and the beginning of the 20th is sufficiently well studied. The subsequent period has not yet been adequately analyzed; there are only partial comments and remarks such as given here. Perhaps, an explanation is that an optimal time for the first serious historical analysis of any period in science comes in 50–70 years after the period to be analyzed, when, on the one hand, all available information is sufficiently fresh, and, on the other hand, a new level of knowledge and a retrospective view enable one to give a more objective analysis (in addition, influences of various mafia groups became weaker). If such an assumption is true, then the time for a deeper historical analysis of the development of measure theory up to the middle of the 20th century is coming. Chapter 1.
