Abstract

There has been an abundance of recent progress in calculating and understanding the ultraviolet properties of supergravity theories. On the calculation side, the duality between color and kinematics proposed in [1] has opened new avenues for constructing supergravity amplitude integrands at relatively high loop order. In this talk, I explain how the color-kinematics duality is used to construct gravity integrands, and I detail how to extract ultraviolet divergences once the integrands are known.
