Abstract
While Feynman integrals and scattering amplitudes are often very difficult to compute directly, their underlying properties point to new approaches. Cuts of diagrams are a tool for their efficient computation, related to unitarity and singularities. I will present definitions and interpretations of cuts, and ways to embed them in new frameworks which can be used to construct the original integrals and amplitudes.
