SUMMARY:Conférence de Nikita Nekrasov - Chaire Aisenstadt 2015
DESCRIPTION:Nikita Nekrasov (IHES/SCGP) est titulaire de la Chaire Aisensta
 dt 2015. Il donnera une série de conférences dans le cadre du semestre t
 hématique «Correspondance AdS/CFT\, holographe\, intégrabilité» sous 
 le thème BPS/CFT correspondance.

\nRésumé de BPS/CFT correspondance\, 14-17 septembre Th
 e non-perturbative quantum field theory and string theory is a source of d
 eep connections between different branches of mathematics and physics. In 
 these lectures I will focus on the correspondence between the generating f
 unctions of instanton invariants\, the integrals over the moduli spaces of
  instantons in Yang-Mills theory in four dimensions\, and the conformal bl
 ocks of two dimensional conformal field theories. The BPS/CFT corresponden
 ce was conjectured around 2002-2004 based on several examples\, which kept
  coming up. The celebrated AGT conjecture (2009) is a particular example\,
  where both sides of the BPS/CFT correspondence are well-known\, but the c
 onnection is surprising. In the lectures I will present the new tool for p
 roving these conjectures\, the moduli space of crossed instantons. In a pa
 rticular corner of the parameter space the BPS/CFT correspondence becomes 
 the Bethe/gauge correspondence\, relating quantum integrable systems and s
 upersymmetric gauge theories. The lectures will report on the latest achie
 vements in this field.
