Michel Duflo
Michel Duflo (born 15 August 1943) is a French mathematician who works in the representation theory of Lie groups. Life From 1962, Duflo studied at the École normale supérieure and received a doctorate under the supervision of Jacques Dixmier. Currently, he is an emeritus professor at the University of Paris VII (Denis Diderot) at the Institut de Mathématiques de Jussieu, and at the École normale supérieure. Duflo has worked on the orbit method of Alexander Kirillov. He introduced the Duflo isomorphism, an isomorphism between the center of the enveloping algebra of a finite-dimensional Lie algebra and the invariants of its symmetric algebra. In 1974 he was an invited speaker at the International Congress of Mathematicians in Vancouver (''Inversion formula and invariant differential operators on solvable Lie groups''). Duflo received the Prix Le Conte of the French Academy of Sciences; in 1986 he became a corresponding member of the Academy. His students include ...

Duflo Isomorphism
In mathematics, the Duflo isomorphism is an isomorphism between the center of the universal enveloping algebra of a finite-dimensional Lie algebra and the invariants of its symmetric algebra. It was introduced by and later generalized to arbitrary finite-dimensional Lie algebras by Kontsevich. The Poincaré-Birkoff-Witt theorem gives for any Lie algebra \mathfrak a vector space isomorphism from the polynomial algebra S(\mathfrak) to the universal enveloping algebra U(\mathfrak). This map is not an algebra homomorphism. It is equivariant with respect to the natural representation of \mathfrak on these spaces, so it restricts to a vector space isomorphism : F\colon S(\mathfrak)^ \to U(\mathfrak)^ where the superscript indicates the subspace annihilated by the action of \mathfrak. Both S(\mathfrak)^ and U(\mathfrak)^ are commutative subalgebras, indeed U(\mathfrak)^ is the center of U(\mathfrak), but F is still not an algebra homomorphism. However, Duflo proved that in so ...

21st-century French Mathematicians
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius ( AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emper ...

Nobel Prize In Economics
The Nobel Memorial Prize in Economic Sciences, officially the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel ( sv, Sveriges riksbanks pris i ekonomisk vetenskap till Alfred Nobels minne), is an economics award administered by the Nobel Foundation. Although not one of the five Nobel Prizes which were established by Alfred Nobel's will in 1895, it is commonly referred to as the Nobel Prize in Economics. The winners of the Nobel Memorial Prize in Economic Sciences are chosen in a similar way, are announced along with the Nobel Prize recipients, and the prize is presented at the Nobel Prize Award Ceremony. The award was established in 1968 by an endowment "in perpetuity" from Sweden's central bank, Sveriges Riksbank, to commemorate the bank's 300th anniversary. It is administered and referred to along with the Nobel Prizes by the Nobel Foundation. Laureates in the Memorial Prize in Economics are selected by the Royal Swedish Academy of Sciences.

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prix Le Conte
The Leconte Prize ( French: ') is a prize created in 1886 by the French Academy of Sciences to recognize important discoveries in mathematics, physics, chemistry, natural history or medicine. In recent years the prize has been awarded in the specific categories of mathematics, physics, and biology. Scientists and mathematicians of all nationalities are eligible for the award. The value of the award in the late 19th and early 20th century was F50,000 (at the time equivalent to £2,000, or US$10,000), about five times as much as the annual salary of the average professor in France. The award was F22,000 in 1984, F20,000 in 2001, €3,000 in 2008, €2,500 in 2010, €2,000 in 2014, and €1,500 in 2019. The Leconte Prize was established with a donation from a businessman, Victor Eugene Leconte, to the academy. The donation specified that a F50,000 prize would be awarded every three years for outstanding past work, and that up to 1/8th of the interest earned by the fund each year co ...
