Perturbative Ultraviolet Calculations in Supergravity
Modern unitarity-based calculations of ultraviolet divergences in supergravity theories have provided valuable data for investigations of the symmetries of these theories. In this seminar, I will give an overview of how these calculations are done. In particular, the colour-kinematics duality provides relatively compact expressions for multi-loop gravity integrands, and I will review some recent progress on obtaining colour-dual forms of Yang-Mills amplitudes at one loop.
