Jean-Pierre Serre (1926 -) – Biography

Jean-Pierre Serre‘s moms and dads, Jean Serre and Ad èle Diet, were both pharmacists. His mom Ad èle had actually been a drug store trainee at the University of Montpellier and she took a calculus course ( simply for enjoyable, she stated, because she liked mathematics) In 1932 Jean-Pierre started his main school education at the École deVauvert It was at the age of 7 or 8 that he started to take pleasure in doing mathematics. In 1937 he moved from the École de Vauvert to study at the Lyc ée Alphonse-Daudet in Nîmes. His mom had actually kept the calculus books that she had actually purchased when she took the mathematics course at the University of Montpellier and Jean-Pierre started to find out mathematics from these books [9]:-.

When I was 14 or 15, I utilized to take a look at these books, and study them. This is how I discovered derivatives, integrals, series and such ( I did that in a simply official way – Euler‘s design so to speak: I did not like, and did not comprehend, epsilons and deltas.)

At this time mathematics wasn’t the only topic he took pleasure in. Although he never ever took much interest in physics, he took pleasure in chemistry which was a subject that his moms and dads, being pharmacists, understood a lot about. In specific his dad had a great deal of chemistry books which Jean-Pierre checked out when he was fifteen or sixteen years of ages. In reality he took pleasure in among these books a lot that he kept a copy of it – this was the book “Les colloïdes”, Gauthier-Villars, 1922 by Jacques Duclaux ( 1877– 1978) However, as he went much deeper into chemistry he ended up being less passionate about the subject and ended up being more persuaded that mathematics was the subject for him.

He discussed his time at the Lyc ée Alphonse-Daudet in Nîmes in [9]:-.

In high school I utilized to do issues for advanced classes. I was then in a boarding home in Nimes, sticking with kids older than I was, and they utilized to bully me. So to calm them, I utilized to do their mathematics research. It was as excellent a training as any.

At the Lyc ée in Nîmes in the year 1943– 44 he had a great mathematics instructor who was nicknamed “Le Barbu” because he had a beard. He was [9]:-.

… extremely clear, and stringent; he required that every formula and evidence be composed nicely.

He coached Serre for the Concours General in mathematics which he beinged in 1944 and was put initially. Also in 1944 he sat the Concours General in physics however because he invested the entire six-hour evaluation utilizing an inaccurate formula, he scored badly. Serre was granted his Bachelier ès sciences et ès lettres in 1944 however stayed at the Lyc ée up until 1945 preparing to take the entryway evaluation to go into the École Normale Sup érieure inParis While at the Lyc ée [9]:-.

I had no concept one might earn a living by being a mathematician. It was just later on I found one might make money for doing mathematics! What I believed in the beginning was that I would end up being a high school instructor: this looked natural to me. Then, when I was 19, I took the competitors to go into the École Normale Superieure, and I was successful. Once I was at “l’École”, it ended up being clear that it was not a high school instructor I wished to be, however a research study mathematician.

From 1945 to 1948 Serre studied at the École Normale Sup érieure and was granted his Agr égé des sciences mathematique in 1948 At this time he ended up being the youngest member of the Bourbaki group of mathematicians. This group consisted of those who had actually been included because the mid 1930 s such as Henri Cartan, Claude Chevalley, Jean Delsarte, Jean Dieudonné andAndré Weil Around the time that Serre signed up with the Bourbaki group, others such as Roger Godement, Pierre Samuel and Jacques Dixmier likewise signed up with.

Serre wed Josiane Heulot ( 1922– 2004) on 10 August 1948; they had one kid, a child Claudine born upon 29 November 1949 Josiane was a natural chemist operating at the École Normale Sup érieure de jeunes filles at Sèvres.

From 1948 to 1954 Serre held positions at the Centre National de la Recherche Scientifique in Paris, initially as attaché and after that as chargé de recherches. In 1948– 49 he participated in Henri Cartan‘s workshop which was on algebraic topology and sheaf theory. Also going to Henri Cartan‘s workshop because year were Claude Chevalley, Jean Delsarte, Jean Dieudonné, Roger Godement, Laurent Schwartz, andAndré Weil One of Serre’s fellow trainees was Alexander Grothendieck and he likewise participated in the workshop. Grothendieck and Serre ended up being buddies at this time. Serre was encouraged by Henri Cartan however [18]:-.

… Cartan did not recommend research study subjects to his trainees: they needed to discover one themselves; after that he would assist them. This is what occurred to me. I discovered that Leray‘s theory ( about fiber areas and their spectral series) might be used to much more scenarios than was believed possible which such an extension might be utilized to calculate homotopy groups.

He was granted his doctorate from the Sorbonne in 1951 for his thesis Homologie singulière des espaces fibrés. Applications Ⓣ In 1952 he went to Princeton where he lectured on the lead to his thesis and likewise on $C$– theory which was the extension of this work. While in Princeton he participated in the Artin–Tate workshop on class field theory. Returning to Paris, he once again participated in the Henri Cartan workshop which, because year, was talking about functions of numerous intricate variables and Stein manifolds. The concepts he satisfied in this workshop inspired the instructions of his research study. In 1953– 54 he was maître de recherches at the Centre National de laRecherche Scientifique

In 1954 Serre went to the University of Nancy where he worked up until 1956 From 1956 he held the chair of Algebra and Geometry in the Coll ège de France up until he retired in 1994 when he ended up being an honorary teacher. He explains in [16] his inaugural lecture at the Coll ège de France:-.

I was a boy, about 30, when I got to the Coll ège. The inaugural lecture was nearly like an oral evaluation in front of teachers, household, mathematician coworkers, reporters and so on. I attempted to prepare it, however after a month I just handled to compose half a page. When the day of the lecture came, it was rather a tense minute. I began by checking out the half page I had actually prepared and after that I improvised.

A couple of months later on he was notified that inaugural lectures were released and he was asked to provide a records. As the lecture had actually been improvised he had no records however attempted to recreate it by offering an unscripted lecture into a tape recorder and after that offering the tape to a secretary to type up. However, the secretary stated that the recording was inaudible. Serre then quit and his inaugural lecture was never ever released. This makes it distinct as every other inaugural lecture at the Coll ège de France that has actually been released.

He has actually likewise discussed his mentor profession at the Coll ège de France ( see for instance [16]):-.

Teaching at the Coll ège is both a wonderful and a tough benefit. Marvellous since of the flexibility of option of topics and the high level of the audience: Centre National de la Recherche Scientifique scientists, going to foreign academics, coworkers from Paris and Orsay – lots of regulars who have actually been coming for 5, 10 or perhaps 20 years. It is challenging too: brand-new lectures need to be provided each year, either on one’s own research study ( which I choose), or on the research study of others. Since a series of lectures for a year’s course has to do with 20 hours, that’s rather a lot.

His irreversible position in the Coll ège de France permitted Serre to invest rather a great deal of time making research study check outs. In specific he hung out at the Institute for Advanced Study at Princeton ( in 1955, 1957, 1959, 1961, 1963, 1967, 1970, 1972, 1978, 1983, 1999) and at Harvard University ( in 1957, 1964, 1974, 1976, 1979, 1981, 1985, 1988, 1990, 1992, 1994, 1995, 1996) Here is a list of the universities where Serre provided courses ( in alphabetical order): Algiers ( 1965, 1966), Bonn ( 1976 ), CalTech ( 1997 ), Eugene ( 1998 ), Geneva ( 1999 ), Göttingen ( 1970 ), McGill ( 1967 ), Mexico ( 1956 ), Moscow ( 1961, 1984), Princeton ( 1952, 1999), Singapore ( 1985 ), U.C.L.A. ( 2001 ), Utrect ( 1974 )

Serre’s early work was on spectral series. A spectral series is an algebraic building and construction like a specific series, however harder to explain. Serre did not create spectral series, these were developed by the French mathematicianJean Leray However, in 1951, Serre used spectral series to the research study of the relations in between the homology groups of fiber, overall area and base area in a fibration. This allowed him to find essential connections in between the homology groups and homotopy groups of an area and to show crucial outcomes on the homotopy groups of spheres.

Serre’s work caused topologists understanding the value of spectral series. The Serre spectral series offered a tool to work efficiently with the homology of fiberings. For this deal with spectral series and his work establishing intricate variable theory in regards to sheaves, Serre was granted a Fields Medal at the International Congress of Mathematicians in 1954 Serre’s theorem caused fast development not just in homotopy theory however in algebraic geography and homological algebra in basic. As an example of Serre’s technique to assaulting an issue, we estimate from the interview[9] Here Serre was addressing a concern about the value of motivation:-.

I do not understand what “motivation” actually implies. Theorems, and theories, show up in amusing methods. Sometimes, you are simply not pleased with existing evidence, and you search for much better ones, which can be used in various scenarios. A case in point for me was when I dealt with the Riemann–Roch theorem ( circa 1953), which I deemed an “Euler–Poincaré” formula ( I did not understand then that Kodaira–Spencer had actually had the exact same concept.) My very first goal was to show it for algebraic curves – a case which was understood for about a century! But I desired an evidence in an unique design; and when I handled to discover it, I remember it did not take me more than a minute or more to go from there to the 2– dimensional case ( which had actually simply been done by Kodaira) Six months later on, the complete outcome was developed by Hirzebruch, and released in his widely known Habilitation thesis. Quite frequently, you do not actually attempt to resolve a particular concern by a head-on attack. Rather you have some concepts in mind, which you feel need to work, however you do not understand precisely for what they work. So, you take a look around, and attempt to use them. It’s like having a lot of secrets, and attempting them on numerous doors.

Over several years Serre has actually released lots of extremely prominent texts covering a large range of mathematics. These texts, which reveal the subjects Serre has actually dealt with, are Homologie singulière des espaces fibrés Ⓣ ( 1951 ), Faisceaux algébriques cohérents Ⓣ ( 1955 ), Groupes d’algébriques et corps de classes Ⓣ ( 1959 ), Corps locaux Ⓣ ( 1962 ), Cohomologie galoisienne Ⓣ ( 1964 ), Alg èbreLocale Multiplicit és Ⓣ ( 1965 ), Lie Algebras and Lie Groups ( 1965 ), Alg èbres de Lie semi-simples complexes Ⓣ ( 1966 ), Abelian l-adic representations and elliptic curves ( 1968 ), Repr ésentations linéaires des groupes finis Ⓣ ( 1968 ), Cours d’arithmétique Ⓣ ( 1970 ), Repr ésentations linéaires des groupes finis Ⓣ ( 1971 ), Arbres, amalgames Ⓣ, $SL _ {2}$

These books are impressive and caused Serre being honoured. In 1995 he was granted the Steele Prize for mathematical exposition and the citation for the award checks out [2]:-.

It is challenging to pick a single work by a mathematician of Jean-Pierre Serre’s stature which is most deserving of theSteele Prize Any among Serre’s many other books may have acted as the basis of this award. Each of his books is magnificently composed, with a lot of initial product by the author, and whatever efficiently polished. It would be difficult to make any considerable enhancement on his expositions; lots of are the daily basic recommendations in their locations, both for working mathematicians and college students. Serre brings his entire mathematical character to bear upon the product of these books; they are alive with the breadth of genuine mathematics and are an example to all of how to compose for impact, clearness, and effect.

The recommendations [8] and [9] supply an interesting view of Serre’s views on some elements of his profession as much as 1985:-.

Presently, the subject which entertains me most is counting points on algebraic curves over limited fields. It is a sort of used mathematics: you attempt to utilize any tool in algebraic geometry and number theory that you understand of, … and you do not rather prosper!

The interview in [8] and [9] likewise offers a possibility to take a look at Serre’s views on mathematics. However, we pick here to estimate from [16] on Serre’s view on applications of mathematics:-.

As for the location of mathematics in relation to other sciences, mathematics can be viewed as a huge storage facility filled with racks. Mathematicians put things on the racks and ensure that they hold true. They likewise discuss how to utilize them and how to rebuild them. Other sciences come and assist themselves from the racks, mathematicians are not worried about what they finish with what they have actually taken. this metaphor is rather coarse, however it shows the scenario all right. (Of course one does pass by to do mathematics simply for putting things on racks; one does mathematics for the enjoyable of it.) Here is an individual example. My partner, Josiane, was a professional in quantum chemistry. She required direct representations of particular proportion groups. The books she was dealing with were not acceptable; they were right, however they utilized extremely awkward notation. I composed a text that fit her requires, and after that released it in book type, as ‘Linear Representations of Finite Groups’. I hence did my responsibility as a mathematician ( and as an other half): putting things on racks.

In the interview [18] Serre discusses his pastimes. He liked rock climbing, snowboarding and table tennis. I [EFR] can definitely state from individual experience what an exceptional table tennis gamer Serre was, for I’ve seen him dipping into lots of conferences that we both participated in. I constantly had the ( extremely ridiculous) idea: How can somebody who is so proficient at mathematics be so proficient at table tennis! Other things that Serre takes pleasure in are chess, checking out books and the films. He stated he liked books [9]:-.

… of all kinds, from Giono to Böll to Kawabata, consisting of fairy tales and the Harry Potter series.

Serre has actually gotten many awards. In addition to the Fields Medal in 1954 he was chosen an honorary member of the London Mathematical Society in 1973, and a Fellow of the Royal Society of London in 1974 He has actually likewise been made an Officer Légion d’Honneur and Commander Ordre National du Mérite. He has actually been chosen to lots of nationwide academies in addition to the Royal Society, in specific the academies of France ( 1977 ), the Netherlands ( 1978 ), the United States ( 1979 ), Sweden ( 1981 ), Russia ( 2003 ), Norway ( 2009 ), Turin ( 2010 ) and Taiwan ( 2010 ) He was granted the Prix Peccot-Vimont by the Coll ège de France ( 1955 ), the Prix Francoeur by the Académie des Sciences ( 1957 ), the Prix Gaston Julia ( 1970 ), the Médaille Émile Picard by the Académie des Sciences ( 1971 ), the Prix Balzan ( 1985 ), the Gold Medal from the C.N.R.S. ( 1987 ), the Steele Prize, explained above, from the American Mathematical Society ( 1995 ) and the Wolf Prize in 2000 He has actually been granted honorary degrees from the University of Cambridge in 1978, the University of Stockholm in 1980, the University of Glasgow in 1983, the University of Athens in 1996, Harvard University in 1998, the University of Durham in 2000, the University of London in 2001, the University of Oslo in 2002, the University of Oxford in 2003, the University of Bucharest in 2004, the University of Barcelona in 2004, the University of Madrid in 2006 and the University of McGill in 2008 In June 2003 he was granted the very first Abel Prize by the Norwegian Academy of Science and Letters [6]:-.

… for playing a significant function in offering a variety of mathematical subjects their modern-day type, significantly geography, algebraic geometry and the theory of numbers.

The occasions surrounding this event are explained in numerous short articles. The following is drawn out from [18]:-.

The occasions began in brilliant sunlight in Oslo on Sunday, 1 June 2003, with a basic event at the Abel Monument inSlottsparken After Jens Erik Fenstad, chair of the Abel Board ( organizer of the reward occasions), had actually provided a brief speech, the Abel laureate, Jean-Pierre Serre, laid a wreath at the monolith. On 2 June the clinical program begun in Georg Sverdrup’s home, the fantastic brand-new library at the University of Oslo inBlindern … Serre’s lecture was entitled “Prime numbers, formulas and modular kinds”. He completely measured up to his credibility as a master expositor, lecturing in the old-fashioned method with chalk on the chalkboard, and amazed everyone with a really clear discussion without notes. … Later in the afternoon, Jean-Pierre Serre got numerous celebrations of reporters for interviews. On Tuesday early morning Serre and agents of the Abel Committee and the Abel Board satisfied the world press: 10 reporters from Norway, England, France, andGermany On Tuesday afternoon the reward existed at an event, with due pomp and scenario, at the University ofOslo King Harald and Queen Sonja participated in, and after some speeches the king provided the reward to Serre.
