The Y-system for scattering amplitudes
 
We compute N=4 Super Yang Mills planar amplitudes at 
strong coupling by considering minimal surfaces in AdS_5 
space. The surfaces end on a null polygonal contour at the 
boundary of AdS. We show how to compute the area of the 
surfaces as a function of the conformal cross ratios 
characterizing the polygon at the boundary. These 
equations have the form of Thermodynamic Bethe Ansatz 
equations. The area is the free energy of the TBA system. 
We consider any number of gluons and in any kinematic 
configuration.
