About 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 LycĂ©e Louis-le-Grand in Paris and graduated in 1966 from the École Normale SupĂ©rieure.
  • He received his doctorate in 1975 from the University of Paris-Sud (Paris 6).
  • 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 Directeur des recherches at the Centre de mathĂ©matiques 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 (which was also proven independently by Gunnar Carlsson and Haynes Miller).
  • The mod p cohomology of the classifying spaces of certain finite groups (elementary Abelian p-groups, for which the generalized Sullivan conjecture was formulated) played an important role in the proof.
  • The connection between the cohomology theory of these finite groups and the classifying spaces of groups is illuminated by the work of Lannes.
  • He introduced the T {\displaystyle T} -functor on the category of unstable algebra over the Steenrod algebra.
  • Lannes thus led an important development of algebraic topology in the 1980s.
  • He has collaborated extensively with Lionel Schwartz, Hans-Werner Henn, and SaĂ®d Zarati. Lannes has also done research on the knot invariants of Vassiliev. He was an invited speaker at the International Congress of Mathematicians (ICM) in Zurich in 1994.
  • His doctoral candidates include Fabien Morel.
  • In 2007 there was a conference in Djerba in honor of Lannes's 60th birthday.
