DESCRIPTION:I will present an exact formula for the thermal scalar two-poi
 nt function in four-dimensional holographic conformal field theories. The 
 problem of finding it reduces to the analysis of the wave equation on the 
 AdS-Schwarzschild background. The two-point function is computed from the 
 connection coefficients of the Heun equation\, which can be expressed in t
 erms of the Nekrasov-Shatashvili partition function of an SU(2) supersymme
 tric gauge theory with four fundamental hypermultiplets.&nbsp\; At large s
 pin the instanton expansion of the thermal two-point function directly map
 s to the light-cone bootstrap analysis of the heavy-light four-point funct
 ion. Using this connection\, we obtain the OPE data of heavy-light double-
 twist operators directly from instanton counting in the SU(2) gauge theory
