Mathematica Summer School on Theoretical Physics

The third day was prepared by Christoph Sieg who lectured on higher loop Feynman diagram computations using both G-functions and the GPXT method. Such computations were very important in the subject of integrability in AdS/CFT in the computation of the 4-loop anomalous dimension of the well known Konishi operator. The exercises covered several examples of the application of these method to the computation of Feynman diagrams appearing at high loop order.
