SUMMARY:Séminaire du LPTMS: Raoul Santachiara - LPTMS\, salle 201\, 2ème 
 étage\, Bât 100\, Campus d'Orsay - 5 Sep 17 11:00
DESCRIPTION:Riemann-Hilbert problem in 2D Conformal Field Theory\nRaoul San
 tachiara (LPTMS\, Université Paris-Sud)\n&nbsp\;\nThe Riemann-Hilbert pro
 blem asks whether the global properties (i.e. their the analytic continuat
 ion) of a space of holomorphic functions allows to determine uniquely the
   linear ordinary complex differential equation (of Fuchsian type) of whi
 ch they are solutions.  The answer is positive for a class of  equations
  that are called rigid systems. We have recently observed that the rigid s
 ystems describe a class of fundamental equations that lie in the heart of 
 the 2D conformal field theories. Moreover we used for the first time a pro
 cedure developed in the last decades for the solutions of rigid systems to
  provide new results in CFTs.  In this talk\, I will try to introduce the
  (beautiful) mathematics behind the Fuchsian systems\, and I will try to g
 ive you an idea of the reason why these equations are related to the confo
 rmal symmetry.
