Jean Lannes (mathematician)
Jean E. Lannes (born 21 September 1947 in Pauligne) is a French mathematician, specializing in algebraic topology and homotopy theory. Lannes completed his secondary studies at the Lycée Louis-le-Grand in Paris and graduated in 1966 from the École normale supérieure (Paris), École Normale Supérieure. He received his doctorate in 1975 from the University of Paris-Saclay (Paris 12). Afterwards he was a professor there and at the Paris Diderot University (Paris 7). In 2009 he became a professor at the École polytechnique and Academic ranks in France, ''Directeur des recherches'' at the Centre de mathématiques Laurent-Schwartz (CMLS); he is now professor emeritus. He was a visiting scholar at several academic institutions, including the Institute for Advanced Study (1979/80) and the Massachusetts Institute of Technology (MIT). Lannes is known for his research on the homotopy theory of classifying spaces of groups. He proved in the mid-1980s the generalized Sullivan conjecture ( ...

Knot Invariant
In the mathematical field of knot theory, a knot invariant is a quantity (in a broad sense) defined for each knot which is the same for equivalent knots. The equivalence is often given by ambient isotopy but can be given by homeomorphism. Some invariants are indeed numbers (algebraic), but invariants can range from the simple, such as a yes/no answer, to those as complex as a homology theory (for example, "a ''knot invariant'' is a rule that assigns to any knot a quantity such that if and are equivalent then ."). Research on invariants is not only motivated by the basic problem of distinguishing one knot from another but also to understand fundamental properties of knots and their relations to other branches of mathematics. Knot invariants are thus used in knot classification,Purcell, Jessica (2020). ''Hyperbolic Knot Theory'', p.7. American Mathematical Society. "A ''knot invariant'' is a function from the set of knots to some other set whose value depends only on the equiva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Staff Of Paris-Saclay University
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philos ...

Lycée Louis-le-Grand Alumni
In France, secondary education is in two stages: * ''Collèges'' () cater for the first four years of secondary education from the ages of 11 to 14. * ''Lycées'' () provide a three-year course of further secondary education for students between the ages of 15 and 19. Pupils are prepared for the ''baccalauréat'' (; baccalaureate, colloquially known as ''bac'', previously ''bachot''), which can lead to higher education studies or directly to professional life. There are three main types of ''baccalauréat'': the ''baccalauréat général'', ''baccalauréat technologique'' and ''baccalauréat professionnel''. School year The school year starts in early September and ends in early July. Metropolitan French school holidays are scheduled by the Ministry of Education by dividing the country into three zones (A, B, and C) to prevent overcrowding by family holidaymakers of tourist destinations, such as the Mediterranean coast and ski resorts. Lyon, for example, is in zone A, Marseille i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Djerba
Djerba (; , ; ), also transliterated as Jerba or Jarbah, is a Tunisian island and the largest island of North Africa at , in the Gulf of Gabès, off the coast of Tunisia. Administratively, it is part of Medenine Governorate. The island had a population of 139,544 at the 2004 census, which rose to 163,726 at the 2014 census. Citing its long and unique history, Tunisia has sought UNESCO World Heritage status protections for the island, and, in 2023, Djerba was officially designated a World Heritage Site. History Djerba is speculated to have been the island of the lotus-eaters where Odysseus was stranded on his voyage through the Mediterranean Sea. Djerba was known as the island of Lytos in the time of the Greeks. It was possible to locate one of its villages from the Qantara Tower, and the name Djerba was given to the area near Houmt Souk.

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the IMU Abacus Medal (known before 2022 as the Nevanlinna Prize), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame".
