\nRésumé de BPS/CFT correspondance\, 14 - 17 septembre 
 The non-perturbative quantum field theory and string theory is a source of
  deep connections between different branches of mathematics and physics. I
 n these lectures I will focus on the correspondence between the generating
  functions of instanton invariants\, the integrals over the moduli spaces 
 of instantons in Yang-Mills theory in four dimensions\, and the conformal 
 blocks of two dimensional conformal field theories. The BPS/CFT correspond
 ence was conjectured around 2002-2004 based on several examples\, which ke
 pt coming up. The celebrated AGT conjecture (2009) is a particular example
 \, where both sides of the BPS/CFT correspondence are well-known\, but the
  connection is surprising. In the lectures I will present the new tool for
  proving these conjectures\, the moduli space of crossed instantons. In a 
 particular corner of the parameter space the BPS/CFT correspondence become
 s the Bethe/gauge correspondence\, relating quantum integrable systems and
  supersymmetric gauge theories. The lectures will report on the latest ach
 ievements in this field.
